The great thing about America is we use both systems as we see fit.

Amen, brother.

Well, personally, I find having the freezing point of water defined as zero and the boiling point as 100 quite intuitive and easy to use. To me, due to my experience growing up in Canada (mostly) after the metric change-over, having the freezing point of water at 32 seems quite counter-intuitive. Kelvins are useful for science (is there an aboslute Farenheit equivalent?) but not very intuitive for day to day use.

1/liters per 100 km =100km per liter/100 = km per liter* how many liters = how many km you can go on your tank.

I remember our teachers telling us in the 60s that the US was going to begin using nothing but the metric system very soon so we had better learn it.

I, too learned metric in elementary school in the late 60's.

It's been marginally useful to me in the 40 years since.

But I never wrote love letters to it, as teachers seemed to want me to back then.

About the same time, AT&T started marketing the "picture phone." Nobody wanted to fool with those, either.

This is America, not Europe. We're the country that broke away from Europe to chart our own course, except when we go back every 30-50 years to clean up the latest Euro-mess.

If I can learn a smattering of German, French and Spanish, they can jolly well learn what an inchworm is.

Only if you're using an uncalibrated force scale (spring scale, stress-meter based scale). A balance-type scale, like a triple-beam, doctor's scale or analytical scale (as used in chem labs) will read correctly in any gravitational field, or constantly accelerating frame of reference, within limits of course. Hmmm, how do you measure mass in a zero-g environment?

...and then all you would have to do is retrieve the exact metes and bounds legal description for every separate parcel of real estate in the United States and re-write all 100 Million or so descriptions based upon your formula. Once you had done that, all that would be left is to contact the holders of all interests of record for each parcel, obtain thier written concurrence and record a new description for each. Simple, actually.

Haha I'm joking. There is a English unit for temperature that starts at 0, but I'm not sure what it is.

They'd have a blast outside the country. I did an AT in the Netherlands with my unit a few years back; I found myself translating the distance signs to the rest of the crew (exits were marked at 300, 600 and 1200 meters). My wife and mother-in-law took a trip south of the border a year or so ago, and all the signs down there were in metric, including the speed limit signs. Your Midwestern friends would find themselves in a target-rich environment the moment they crossed the U.S. border outbound.

It does raise the question, though - why l/100km, rather than km/l? Either works, but the latter is much more intuitively comparable and convertible to mpg than the former.

Ha ha or you could leave it the way it was. There's no reason some English could be used, just because its a pain to switch. Or computerize the entire process, it would be monumental but would end up saving time in the long run.

It's based on mercury. He was trying to scale his mercury themometer for maximum use. 0 deg F is as cold as he could make it and he tried to make 96 deg normal human body temp, so he could detect fevers.

Kelvins are useful for science (is there an aboslute Farenheit equivalent?)

Rankine. Same size degree as F, but zeroed at absolute. R=F+459.67

Yea I have no idea, but thats not a metric system fault its whoever chooses to report their fuel efficiency in those units. Personally I'd do it just like you said km/liter.

100 km per liter is about 230 miles per gallon, if I've done my calcs correctly (100 km = ~60 miles and one gallon = ~3.8 liters; ~380 km/gallon).

The traditional or Imperial units were all based on practical applications -- metric tries to force everything into powers of ten. When Canada converted to metric, we had "soft" conversions for many things -- e.g. a pound of butter became 454 grams (close enough). Now, we buy butter in 500 gram packages -- in effect a "metric pound", although no one calls it that. A kilogram would be too big, a hectogram (100 grams) too small. Similarly, a gallon was a good size for a jug of milk -- 10 litres would be way too big. The metric system has had to adapt to the way people actually do things.

Wasn't it always easier just to remember that: "a pint's a pound the world around"?

Just do the conversions when the property changes hands. The new deeds would have the new measurements. It wouldn't need to be done overnight, and converting every parcel of land in the country could take a couple of generations (land doesn't necessarily change hands every day).

You're right about the importance of precision and reliability for manufacturing, international trade, etc. However, Seaver Leslie (mentioned in the article) is also correct in saying that the "standard" units are "human-based" and have history. The metric system is based on an abstraction -- humans have had to adapt to it.

Thanks, right, Rankine, as in the Rankine cycle, which I vaguely recall from the Thermodynamics texts.

I've always liked the metric system;

Me too (French wines, as well), but it depends on what I'm doing. I can't imagine doing chemistry using English measures, but like to use inches, halves, sixteenths, etc. when building houses, and prefer having both standards available.

Great. My 160 acre farm would become a 64.749702 hectare farm.

If I were to give half my farm to my son, we would each have 80 acres under the confusing old English system, but 32.374851 hectares under the French system. A subsequent division would yield 40 acre farms under the English system or a far easier to work with 16.1874255 hectares using the french system.

You got me convinced.
