I have lived in a variety of countries, and one thing that I have noticed is that, even with the language barriers, it is easier to find out how tax dollars are being spent and what the government is doing. Partly this is because some governments put more effort into communicating with their citizens.

And partly it is because the math is easier elsewhere.

I was originally going to start my first post by comparing irrigation calculations. They are easy using metric measures and insanely hard in US customary. But I can't find the U.S. calculations. Neither the US Department of Agriculture nor the Colorado Agriculture Extension office have any basic information on irrigation. Large parts of Colorado, especially in the south east, are currently experiencing severe drought conditions. And farmers have no easily available source of information about how they are using water.

This unwillingness to believe that some basic things can be understood has deep roots in our history. Evidence (via The Metric Maven) comes from hearings on the metric system that Congress held from 1904-1906. Herbert Davidson, a metrication supporter, represented a company that made library supplies, and he had the following exchange with Rep. John W. Gaines of Tennessee:

Mr. Gaines. ….when I went to school my teacher very properly, I think, skipped me over the metric system, and they did not teach it then. Would we not all have to go to school and learn the metric system before we could know whether or not we were getting true measure according to the old standard?

Mr. Davidson. I think that a person of ordinary intelligence who gave five minutes to the subject of the metric system would be able to comprehend it. [Laughter.]

Mr. Gaines. How long have you studied it?

Mr. Davidson. I must say that I never spent fifteen consecutive minutes over it.

Mr. Gaines. Well, you are an expert by nature.

(Mr Davidson then attempts to explain the metric system to Mr. Gaines)


Mr. Davidson. Why, I chose to use the metric system is because it impressed me as being simpler.

Mr. Gaines. When did you first undertake to study the metric system?

Mr. Davidson. I say I never studied it.


Mr. Gaines. ….. The people of the United States, at all events would have to first learn the metric system before they could use it. Now, this is what I am trying to find out—they would have to learn the difference between a foot and a meter and a yard and a meter and a pound and a meter, and so on. They would have to do that certainly.

Mr. Davidson. They would have to gain some knowledge of the metric system; but it all appeals [appears?] to me, sir, as being so exceedingly simple that I cannot comprehend the intelligence that can not understand what a meter is, what a liter is, and what a kilo is.

Mr. Gains. But you must remember that we are not all college graduates, unfortunately for us; and I take it that you are.

Mr. Davidson. Neither am I.

I think that fact that Rep. Gains thought you had to go to college to understand metric and that basic information about irrigation is hard to find are related. If you believe that ordinary people cannot understand ordinary things, then it does not matter if basic information is not available to those people.

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.

    Highway signs began to appear in the US that displayed both English and metric distances. The Know Nothings went crazy, and raised such a big fuss that the signs were taken down. Four decades later, the kilometer is still a puzzling concept to many Americans.

      switched to liter drink bottles and no one raised a fuss. Maybe because they are a little bigger than the old quart bottles. And a lot of guns are measured in mm and the wingers think that's nifty.

      Cars are all metric. Trucks are changing over. Computers are all metric. The US is halfway to being metric already!

      I once read an essay that said the inch and foot were better units for craft work because they related to the human hand and arm. Maybe, but the ease of base ten math will always give the edge to metric IMO.

        Is that all of our measures go back about three thousand years and are not only commensurable between systems, periods, countries, languages, and dimensions of time and space but also geo-commensurable

        The proportion of foot to remen can be either 4:5 making it the hypotenuse or 3:4 making it the side of a right triangle. If the remen is the hypotenuse of a 3:4:5 triangle then the foot is one side and the quarter another so the proportions are 3:4 quarter to foot, 4:5 foot to remen and 3:5 quarter to Remen. The quarter is 1/4 yard. The foot is 1/3 yard. The remen is

        The remen may also be the side of a square whose diagonal is a cubit The proportion of remen to cubit is 4:5

            The proportion of palm to remen is 1:5
            The proportion of hand to remen is 1:4
            The proportion of palm to foot is 1:4
            The proportion of hand to foot is 1:3

        in addition to similarities between body measures and agricultural measures and between the system used in Mesopotamia four thousand years ago, the systems also allow measures of length, area, and volume to be commensurable so that "A pint's a pound the world around"
        The table below demonstrates a harmonious system of proportion much like the musical scales, with fourths and fifths, and other scales based on geometric divisions, diameters, circumferences, diagonals, powers, and series coordinated with the canons of architectural proportion, Pi, phi and other constants..
        Go to the link for the table
        In Mesopotamia and Egypt the Remen could be divided into different proportions as a similar triangle with sides as fingers, palms, or hands. The Egyptians thought of the Remen as proportionate to the cubit or mh foot and palm.

        They used it as the diagonal of a unit rise or run like a modern framing square. Their relatedseked gives a slope. Its convenient to think of remen as intermediate to both large and small scale elements.

        Even before the Greeks like Solon, Herodotus, Pythagorus, Plato, Ptolomy, Aristotle, Eratosthenes, and the Romans like Vitruvius, there seems to be a concept that all things should be related to one another proportionally.

        Its not certain whether the ideas of proportionality begin with studies of the elements of the body as they relate to scaling architecture to the needs of humans, or the divisions of urban planning laying out cities and fields to the needs of surveyors.

        In all cultures the canons of proportion are proportional to reproducable standards.

        There are twice as many seconds in a century as there are inches in the circumference of the earth at the equator, as nearly as can be measured allowing for things like tides and the rise of sea levels due to global warming.
        In ancient cultures the standards are divisions of a degree of the earths circumference into mia chillioi, mille passus, and stadia.

        Stadia, are used to lay out city blocks, roads, large public buildings and fields

        Fields are divided into acres using as their sides, furlongs, perches, cords, rods, fathoms, paces, yards, cubits, and remen which are proportional to miles and stadia

        Buildings are divided into feet, hands, palms and fingers, which are also systematized to the sides of agricultural units.

        Inside buildings the elements of the architectural design follow the canons of proportion of the the inscription grids based on body measures and the orders of architectural components.

        In manufacturing the same unit fraction proportions are systematized to the length and width of boards, cloth and manufactured goods.

        The unit fractions used are generally the best sexigesimal factors, three quarters, halves, 3rds, fourths, fifths, sixths, sevenths, eighths, tenths, unidecimals, sixteenths and their inverses used as a doubling system

        Greek Remen generally have long, median and short forms with their sides related geometrically as arithmetric or geometric series based on hands and feet.

        Whats interesting about this is that you can look at modern European measures and tell whether it was the Greeks or the Romans to whom they owe their standards of measure.
           The Egyptian bd is 300 mm and its remen is 375 mm. the proportion is 1:1.25
            The Ionian pous and Roman pes are a short foot measuring 296 mm their remen is 370 mm
            the Old English foot is 3 hands (15 digits of 20.32 mm) = 304.8 mm and its remen is 381 mm
            The Modern English foot is 12 inches of 25.4 mm = 304.8 mm and its remen is 381 mm (15")
            The Attic pous measures 308.4 mm its remen is 385.5
            The Athenian pous measures 316 mm and is considered of median length its remen is 395 mm
            Long pous are actually Remen (4 hands) and pygons
            See cubit for the discussion of the choice of division into hands or palms
            See the table below for proportions relative to other ancient Mediterranean units

        Roman Remen generally have long, and short forms with their sides related geometrically as arithmetric or geometric series based on fingers palms and feet.

        By Roman times the Remen is standardized as the diagonal of a 3:4:5 triangle with one side a palmus and another a pes. The Remen and similar forms of sacred geometry formed the basis of the later system of Roman architectural proportions as described by Vitruvius.

        Generally the sexagesimal (base-six) or decimal (base-ten) multiples have Mesopotamian origins while the septenary (base-seven) multiples have Egyptian origins.

      •  Dual measures aren't hard (0+ / 0-)

        You can for example start with a foot of 300 mm and divide that into hands of 100 mm or palms of 75 mm. Either three hands equals a foot, five hands equals an ordinary cubit and six hands a sacred cubit, or four palms equals a foot, five palms equals an ordinary cubit and seven palms equals a royal cubit. Two ordinary cubits equal one meter, two feet equal one ell or a sacred cubit.

        The body measures can be dual with agricultural measures, three feet equal a yard, five feet equal a pace six feet equal a fathom and also with standards of measure that relate time to distance such as a days march or a days sail.

        Anciently all of these measures were used as unit fractions
        and related to degrees so that a Greek stadion or a Roman stadium of 185 m could be combined to make a mia chilios, miliare or mile of 8 stadia or 1000 paces with 75 miles to a degree.

      Recommended by:
      elfling, RiveroftheWest

      Are you sure?  A furlong is 660 feet - just over 200 meters.  What the heck do you build and sell, battleships?

      By the way, for the customary-unit challenged, an acre is 1 furlong X 1 chain, or 660 feet X 66 feet.  At 43,560 sq feet, you have a crazy-divisible number.  A valuable property for something as valuable as, say, property.

      It seems to go unmentioned in the post or in the comments that the metric system is devised for ease of multiplication (though, of course, all numbers can be multiplied by all others) while our customary system is devised for ease of division (since some integers just can't be combined to divide back into rational numbers - for example, 10 cannot be divided by 3).

      Both systems have their merits, but there can't be debate that you can literally perform more operations in customary measures (all the same ones you can do in metric, plus more factoring) than in metric.  Whether that's important, though, is another question.

    I have always believed in mathematics as the "universal language", in that people can communicate effectively as long as there is an agreed-to set of axioms first.

    The metric system is the "axiom" that allows for effective scientific communication (sorry for all the scare quotes).

    BTW, I fixed the S.T.E.M. calculator from my post yesterday. Thanks for pointing out that I was using (gasp) pounds instead of grams in a science project!

  •  How much is an acre-foot, anyway? (9+ / 0-)

    There are a lot of strange units out there.

    Furlongs per fortnight isn't that difficult after you've dealt with a few of them, but metric does generally simplify things a lot. And the multipliers are dead useful.

    E (exa) 10^18
    P (peta) 10^15
    T (tera) 10^12
    G (giga) 10^9
    M (mega) 10^6
    k (kilo) 10^3
    m (milli) 10^-3
    u (micro) 10^-6
    n (nano) 10^-9
    p (pico) 10^-12
    f (femto) 10^-15
    a (atto) 10^-18

    and there are now units for 10^+-21 and 24.

    More than once, I've had vendors quietly change units on me, hoping I wouldn't notice. IIRC, I was once unkind enough to re-request a bid after I re-specced the bandwidth units in bits/attofortnight.

      For those not accustomed:
      An acre foot is enough water to cover an acre with 12 inches of rain.

      In my water district, which is northern California, pastures use, on average, 4.32 acre feet of irrigation water per acre per year, pears use 3.48, row crops use 3.57 and vineyards use 2.07 acre feet of water per acre per year. (These numbers include frost water.) These numbers do not include the water they naturally get from winter rains.

      •  And we are likely stuck with acre-feet (5+ / 0-)

        for a very long time. The underlying measurements for every piece of property in the US are the English units: feet for linear dimensions, and acres or square feet for the area measurements. All of the deeds and plats recorded in our courthouses are in these units. Changing to meters and hectares would be a monumental task.

        Canadians still refer to acres, even though their country has been metric for a long time.

        Probably the best we can do is to convert to acre-centimeters, or acre-meters.

        My intended (but perhaps poorly made) point was conversions to and from that unit to more familiar units are likely to be known only to someone who does those conversions regularly.

        For many calculations, it's immanently reasonable. However, converting to or from gallons or cubic feet or cubic yards or liters or any more familiar unit is likely to be peculiar.

        A unit like a hectare-meter, conversely, would be straight-forward to convert to liters or cubic meters.

          but it shows why a unit that seems completely peculiar remains in widespread use - because it's very convenient in real life.

          The ability to convert between cubic feet and acre-feet seamlessly is less important than the ability to specify the amount needed simply and accurately, in a way that makes error obvious. If I were to specify the water I needed in gallons or cubic meters, I could make an error by a factor of 10 and not catch it right away because it isn't intuitive. But no one is going to accidentally ask for 10 acre feet when they meant 1 acre foot.

        •  That's because you're not irrigating acreage (3+ / 0-)

          It makes a lot of sense if you know your crop needs 12 inches of water a month during summer months and you're irrigating X acres. And that's exactly how people understand it and use it.

          1 acre foot times 20 acres: easy peasy.

          1233.5 cubic meters times 20 acres... um ... 24670 m3. Um, yeah. Intuitive. 25,000 cubic meters of water is much harder to visualize and understand, and if someone said, how about 20,000 m3, you don't have the same visceral understanding of what that will mean to your crop.

          The nice thing about acre-feet is how easily it converts in your mind to rainfall - large unit of land area times the amount of rainfall that fell on it, as an equivalent volume of water.

          I'm an engineer, and I'm comfortable and acquainted with metric, but it's worth appreciating that people use other units for real reasons, not just because Daddy Did.

      •  The acre is one of the earliest units of measure (2+ / 0-)
        Recommended by:
        elfling, eyesoars

        It starts out as the Mesopotamian iku, becomes an Egyptian 3kr, goes on to Greece as an are and Rome as an area. It didn't become 43,560 square feet till Queen Elizabeth 1 changed the length of the English mile from the old myle which was at 5000 foote the same length as the Roman miliare or the Greek Mia chilios.

        Anciently fields were planted in groups of two if plowed with an ox or three if plowed with a horse which allowed one to be left fallow.

        The Greek root stadios means 'to have standing'. Stadions are used to measure the sides of fields.

        In the time of Herodotus, the standard Attic stadion used for distance measure is 600 pous of 308.4 mm equal to 185 m. so that 600 stadia equal one degree and are combined at 8 to a mia chilioi or thousand which measures the boustredon or path of yoked oxen as a distance of a thousand orguia, taken as one orguia wide which defines an aroura or thousand of land and at 10 agros or chains equal to one nautical mile of 1850 m.

        Several centuries later, Marinus and Ptolemy used 500 stadia to a degree, but their stadia were composed of 600 Remen of 370 mm and measured 222 m, so the measuRement of the degree was the same.

        The same is also true for Eratosthenes, who used 700 stadia of 157.5 m or 300 Egyptian royal cubits to a degree, and for Aristotle, Posidonius, and Archimedes, whose stadia likewise measured the same degree.

    You can use decimals[and confine yourself to one unit for each measure] with the US units as well.  Personally I think it is whatever you are used to much like a mother language.   One difference that is material for daily use is the granularity of the various measures.  I like Fahrenheit over Celsius because I think I can tell the difference between 1 degree F, so 1.8 degrees seems like to big of a granular difference.  Similarly I like the pound more than the kilogram because the kilogram seems to big.  On the flip side, the gram is better than the ounce, because once you decide to measure small things the smaller unit is preferable.  You can't really say it makes sense that the basic unit of mass for daily use is one thousand of another unit.  I don't really use liquid measures so I tend to default to liters there.  I of course also use ounces/gallons, but never in situations where I have to mix more than one unit.  I prefer the foot to either the meter or the yard for granularity reasons.  I also prefer the mile to the kilometer, but I can't really articulate a good reason for that.  

    Of course what we use for cooking is rather silly, but it works. It mostly has to do with granularity.  You pretty much always use 1/2, 1, or 2 of each unit.  What even is the metric alternative to dry measures?  cubic centimeters?  Yes I know that is the same as a mililiter, but you aren't supposed to measure dry stuff the same as liquid stuff.

    There are certain constants I only know in metric since they derive from science which uses metric.  Density of water, speed of light, acceleration under earth's gravity, atoms in a kilogram of hydrogen.  But really I don't use those on an every day basis.

    I also was looking over the wiki page on metric and they seem to be using the british spelling of meter and liter which just makes me want to barf.

      to and from some original units to whatever units the calculation gets made in is a trivial step.  However, the problem is that this is one more step in which a catastrophic error can be made, particularly where complex systems are involved.  Let's take health care as an example.  Doctors still measure their patients' weight in pounds using scales show only pounds (in the US).  Any calculation for a drug dosage is going to require a conversion to kg because it is pretty much universal that dosage recommendations are scaled to standard units such as mg/kg of lean body weight, etc.  Now imagine that someone in the chain of custody misses that pound/kg conversion.   The patient could end up with a double dosage which depending on the medication could be toxic.  So there are definitely valid reasons why the metric system should be extended to more parts of the layperson's daily life.

    •  You are exactly right (0+ / 0-)

      Think of it in terms of cooking. When you want to double a recipe if you can do so to accommodate the size of pots or pans and instantly know how it is related to time and  things like doubling cubes and squaring circles and trisecting angles easy to do in your head, ordinary people like cooks and bakers, and brewers  can figure how many bushels of grain or hops and how many oz of yeast they need to make how many loafs of bread or casks of ale.

      Carpenters and masons can use the tables on a framing square to instantly determine  unit rise and run or figure out what the circumference of a circle is from its diameter using a formula for Pi that instead of 3, which is inaccurate or 3 1/7 which is hard to measure 3, 1/8, 1/64 which is both easy to measure and accurate.

  •  I deal with several measurement systems. (3+ / 0-)

    "Traditional US" measurements (inch, foot, yard, gallon, cup, ounce, mile, degrees Fahrenheit, etc), some metric, typographic measurements (point and pica), and "screen measurements" (pixels).

    They are all intended to measure different things. It might be convenient to have one system to rule them all, but it isn't actually possible (particularly in pixel-land).

    I don't use units of measurement intended to measure a horse. Or weights in the UK (stone). Or nautical measurements. Or astronomical measurements.

    Changing to metric is like changing currency. People understand what the old system means and the new one has no points of reference or set "value." To my experience, degrees C don't have enough subtlety - they encompass too much change in each degree. But centimeters are too small - looking at the individual trees in the forest. There is no metric equivalent of a foot, which is a unit I understand. From my experience. It doesn't matter if MY foot is that size, I understand that particular unit.

    All my cookbooks (with some European exceptions) use Imperial measurements and I don't have a scale to weigh my food. I have drawers full of measuring spoons and cupboards of measuring cups, and I've figured out how many Ts are in a C. :-)

    It is easy to comprehend the CONCEPT of metric, but it isn't always as easy to apply it to your EXPERIENCE.

      The F/C subtlety thing is ridiculous. I've had this argument with people for far too many years.

      If you can tell the difference between a 63 and 64 degree Fahrenheit day, you're special. If you're that special, you can use 0.5 degree Celsius increments. They're even finer that Fahrenheit - 0.9 F to be exact.

      My car does this as a matter of fact. My temperature display uses 0.5 C or 1 F increments.

      As for other units, it's just a matter of developing a new frame of reference. Use the units more and you get used to them. It's happened in every English speaking country that's fully converted since the late 1960s. Canada's been held back from full metrication due to the botched US conversion, but they do use degrees Celsius and metric for car distances.

      The cooking problem is one of volume (US cups) versus mass/weight based recipes, which metric recipes typically are. Metric volume based recipes exist - look at Australian and Canadian cookbooks.

        I don't have a frame of reference.

        So you can dismiss people as silly or lazy or stupid who don't "like" or "understand" the new frame of reference, but it is real.

        It isn't whether the difference between 63 and 64 degrees is something I can distinguish. On any given day, 63 may feel very different than 63 the day before or the day after. It is that the calibration of my body and mind's understanding of what it means is part of my frame of reference that isn't going to shift. It is like counting in a foreign language. Even people fluent in foreign languages will often count in their native tongue, particularly if they are like many students of foreign language in the States: learned it late in life.

        So yes, metric, blah blah, easy to divide by ten, blah blah. Rationally I agree, but the whole point is perhaps that this is not rational?

        •  You can develop it. (0+ / 0-)

          You choose not to. Learning to use everyday metric is much easier than learning a new language.

          You've learned to use the internet. You've probably learned to use digital music. Doesn't mean you've forgotten how to use a dial telephone or play an LP.

          That 63 degree Fahrenheit day you distinguish above is the same (for all intents and purposes) if you express it as 17 degrees Celsius. It's just that you have a problem accepting that 17 is the same as 63 in the context you describe.

          •  You are missing my point. (4+ / 0-)

            OF COURSE I can learn the frame of reference. So can anyone. OF COURSE it is easier than learning a new language.

            Your point seems to be that I am too lazy and/or stubborn to change my frame of reference.

            My point is that I have spent a lifetime with this frame of reference and it makes sense to me. Changing this frame isn't as tragic as governments forcing people to learn the "official" language in order to suppress their own and therefore kill their culture. But the emotional relationship people have with their cultural tappings is real, not necessarily LOGICAL.

            There is cultural mystique built into the furlong or the nautical mile or the knot or the hand or the stone or the pint. To deny their importance is to make the path to metric-ization harder. People fight back when you don't acknowledge their irrational attachment to a cultural norm.

            I have a kitchen full of old cookbooks with favorite recipes I have no interest in replacing; a cupboard full of free-to-me old measuring devices I have no money to replace. The highway signs continue to be imperial. At this point in time, there is no reason for me to change my frame of reference when everything about me reinforces my old one, as illogical as it is.

            It is funny how people get ideological about this stuff. Why do you want to denigrate me because I like the system I lived with my entire life?

              Your unwillingness to incorporate a new frame of reference into your thinking is stubbornness, pure and simple. It's you that's attaching extreme amounts of cultural significance to a technology - a tool.

              Just because there's digital music doesn't mean that some people don't enjoy listening to records. However, in 2013, they are a niche pursuit. Likewise, in a metric world, our use of imperial units (as a society) is an anachronism.

              It costs us money and time, and makes us less numerate as a people. What's longer? One mile, 2000 yards, 7000 feet or 80000 inches? You have to do mental gymnastics to answer the question.

              If you insist on using imperial measurements, you can. A metric US won't change that. Your non-metric cookbooks still work if you buy your ingredients in metric. A teaspoon is 5 ml, so your spoons won't even have to change.

              You may (gasp!) have to learn and internalize something new, but you'll understand two systems instead of one. Why do you insist on forcing everyone else to learn two systems to satisfy your personal whims? You do the work instead if you want to. Metric isn't going anywhere.

              I say whatever cultural loss there is is not worth the ongoing hassle. Literature isn't going to change. Dickens still uses predecimal British currency, even though there hasn't been a shilling since 1971.

              We need to rip this bandage off once and for all. The onus should be on those who want to continue to use imperial units to do the conversions themselves.

          Also, while there's 16 US fluid ounces in a US pint, there's 20 imperial ounces in an imperial pint. Oddly, that makes an imperial fluid ounce smaller than a US fluid ounce and also makes an imperial ounce of water equal to an ounce of weight.

      ...but you've come up with the wrong solution.

      You get used to metric the same way you got used to imperial units - by feel. This is the way successful metric conversions have been handled around the world - people are encouraged to get a feel for the new units during the conversion period (10 years typically).

      You probably already know a meter is a little bigger than a yard, a liter a little bigger than a (US) quart and a kilogram a little bigger than 2 pounds.

      So a very rough conversion for your coffee can and bag of feed is 500 g (half a kilo) and 25 kg. Good enough to give you an idea of the metric equivalents. By getting a feel for the different units, you don't have to do exact conversions except when precision is needed.

      It's very fair to say doing math is difficult for a lot of people. Why continue to torture future generations of Americans by insisting they know that there's 12 inches in a foot, but 3 feet in a yard and 1760 yards in a mile?

So much of US manufacturing is already metric, and things like gas pumps and scales can be converted by flipping a switch and applying some stickers.

    I’m American, and I know if you’re driving 60 mph, a rule of thumb is 1 mile is 1 minute. If the sign says 180 miles, that’s 180 minutes (3 hours). Right? Look at the clock and add three hours (if you’re not stopping for gas or lunch).

    In Canada, the signs are in kilometers. I was driving about 60 mph, which is really close to 100 kilometers per hour. So here‘s what you do: just move the decimal two points to the left. 250 km becomes 2.5 (two and a half hours). 75 km (.75) is three-fourths of an hour, or 45 minutes. And so on. A simple solution. You don't have to convert to miles. Just move the decimal point over.


    Temps in Canada

    Another trick for Canada. If the radio announcer gives the temperature in Celsius, double it and add 30 to get the Fahrenheit equivalent. If they say 11 Celsius it’s 22+30. About 52. -5 C is -10 plus 30 or about 20 Fahrenheit. (Note: to get it perfect, you should really multiply by 9/5 and add 32, but the rule of thumb gets you close enough).


    Imagining an acre

    For many years I never knew what an acre was. I knew it was a measure of land, but I couldn't imagine how big it was. Then someone told me this:

    An acre is the size of a standard American football field without the end zones.
    I did the math. It was within about three or four percent plus or minus. Bingo! I can now imagine an acre in my head. So when someone says 20 acres, I think of four football fields across and five deep. 10 acres is slightly  bigger than 3x3. And so on.


    Converting Units

    I’m not scared by math and I can often do math in my head. However, I learned a great trick from a chemistry teacher in high school.

    He taught us that if x=y, then x/y or y/x will always equal 1 (for example, 16 oz/1 lb or 1 lb/16 oz). And you can cancel out the units if the unit is in the numerator (the top) on one and the denominator (the bottom) on the other.

    And multiplying by 1 doesn’t change the number. So you just multiply by one as many times as you need to. For example, let’s say you need to convert 3 ounces into grams.

    3 oz x (1 lb/16 oz)  x (1 kg/2.2 lb) x (1000 g/1 kg) and then you cross out the units -- ounces cancel out and so do pounds and kilograms, leaving you with grams. So it’s (3 x 1 x 1 x 1000)/(1 x16 x 2.2 x1) -- and you get whatever the answer is to two significant digits.


    It makes more sense if you write it out this way:

    3 oz    1 lb       1 kg     1000 g
            x  --     x      --   x    ---       =   85 grams
              16 oz      2.2 lb     1kg

    Cross out oz and oz, lb and lb, kg and kg (on the top and bottom) and you're left with grams.

  •  What is great about the metric system is that it (2+ / 0-)

    lends itself to easy exponential scales of magnitude usually in increments in mags of 3.  Beautiful.

  •  Not a matter of logic (4+ / 0-)

    If it's just a question of logic, then there's nothing to discuss. For simplicity's sake, most industries are already using metric - particularly multinationals. Maintaining the Imperial system causes too many headaches in calculations.

    But it's not just a matter of logic.

    Our Imperial system of measurement is built into our language, literature, and history. It's in our music and art. Generally, a native speaker of English will have a visceral feel for what a "mile" is. A kilometer (or 'klick" or what have you) is an artificial thing - easy enough to grasp but you have to do a mental calculation (3/5 mile).

    So some metric geek comes skipping up, "You should switch to metric! The whole world uses metric! It's better, it's more logical!"

    Fuck off. Ain't gonna happen.

    Instead, we'll probably have both systems in use in the US for decades yet to come, just as the Japanese maintain 4 separate syllabaries for writing, dual counting systems, etc. It's simple enough to use metric for calculation-intensive purposes and Imperial for general tasks and cultural material.

      I were younger, I would learn more metric measurements and use them until they came "naturally". But I said the same thing 25 years ago, and didn't... maybe another generation or two has to shuffle off before the US is ready for metric.

    •  Well, it won't happen by osmosis. (1+ / 0-)

      We tried that when the Metric Conversion Act of 1975 was borked when some sly legislator got the word "voluntary" inserted into the final language.

      You do it right and it becomes part of the culture. See Australia, New Zealand and South Africa, which all converted in the late 1960s and early 1970s. In Canada, metric conversion got far enough along where people think in degrees Celsius and in metric for long distances.

      Each country used a 10-year mandatory plan. Conversion itself was mandatory - how individual industries and public sectors got there was up to the industries/sectors themselves. Canada's conversion pooped out near the end due to a Conservative government and lack of a mandatory US conversion plan. Still, for the most part I can get by in Canada with only metric measurements.

      Although it may not be too much of a pain in the ass to use imperial units for everyday tasks (for the numerate), it is harder than metric.

      Here's an example I like to use. Your room is 14' 3-1/4" by 12' 6-5/8". How many square yards of carpeting do you need to cover the floor?

      (Let's rule out "fuck if I know, I'll call up Lowe's" and "I want a bamboo floor instead" as valid answers.)

  •  Doesn't BuRec have all the irrigation data? (2+ / 0-)
    Recommended by:
    elfling, ybruti

    Not sure exactly what you're looking for, but in the West the Bureau of Reclamation has most of the responsibility for irrigation. Their records may contain what you're looking for.  They even have historical datasets available, such as this one for 1979-1986. The land grant universities often have data as well, such as this site for Nebraska. If you dig around at BuRec you may well find that the data you want is buried there somewhere; at least they have a series of photos of irrigation projects on the Lower Colorado.

    All that said I entirely agree with you re the metric system and the problem with finding data. As a frequent user of government environmental data I find I waste a lot of time just trying to figure out which agency might even have the data I need, then more time trying to locate it, then often even more time trying to unpack it from whatever arcane and no-longer-support file system that have stored it in. Much of this is due to the inane and incompatible data systems maintained by the US government, and the lack of consistency between agencies.

    Metric of course makes sense. But it's also true that the American West is the source of many of our "standards" and laws with regard to natural resource management, including the acre-foot and the Animal Unit Month. Changing those systems would require not only adopting new standards but often rewriting statutes as well since many of them were expressly codified by Congress in the late 19th and early 20th centuries.

  •  As a Learning Support Teacher (4+ / 0-)

    tasked with teaching students with learning disabilities Principles of Technology (Entry level Physics) in the English and Metric Systems simultaneously, I can tell you that our insistance on sticking with the English system is hurting our kids.  Imagine learning Shakespeare in English and Chinese simultaneously!

    I understand and can appreciate the resistance to changing, however, this issue is not about the present.  This issue is about preparing for the future.  Eventually, the English system will be studied only in history class--industry has been converting for decades.

    metric.  For the first time units of measurement, especially weight and volume, made sense.  All I had been taught about the metric system was that it is 10's based.  That's all I needed to know to put it to use.

  •  We have a standing joke in our house (3+ / 0-)
    Recommended by:
    elfling, ybruti, RiveroftheWest

    that whenever we discuss a hypothetical mathematical situation, we put it as a word problem with absurd animals at speeds or distances in metric. This is based on my daughter's science class word problems to teach distance=rate x speed.

    So tonight I bust everyone up at the table after the obligatory "If you have a bumble bee flying 7km/hour and an ostrich running the 100m dash..." by asking "what is the metric for time?" Because you know this whole 60 seconds/minute, 60 minutes/hour, 24 hours/day and 12 v 24 hour clock thing is pretty darned illogical. The best part is that they thought my question was serious.

  •  I go back and forth... (1+ / 0-)

    Like when I do woodwork, I'll go back-and-forth between mm's and fractions of an inch.  

    Also, I know that the Metric system is so awesome and rad in the abstract, but:

    I can walk a mile in exactly 15 minutes

    I am almost exactly one fathom (6 feet) tall.  I have no idea what I am in meters.

    I try to drink 8 cups (1/2 gallon) of water a day.  I have no friggin' idea what that is in litres!

    My forearm is almost exactly 11 inches.  What is it in centimeters?

    You get the idea...
