Consider the use of the Elizabethean measures in the U.S. an artifact of
"freedom of expression." Probably with a mix of anarchy, contrariness and
rebellion thrown in. It's kinda fun to watch Arlo Guthrie protest the
metric system in concert with "Inch By Inch, Row By Row." While the metric
system has been accepted legal and standard measure in the U.S. for over a
hundred years, we haven't legislated it to be the only national system of
measurement. Russ Rowlett does a much better job than I in explaining the
vagaries of the U.S. and the metric system,
http://www.unc.edu/~rowlett/units/usmetric.html .
To add to my mental density and confusion, first, the last time I was out of
the U.S. most (if not all) of the Commonwealth countries still used Imperial
measure and the U.S. dollar was backed by gold and, second, the computer
typeface uses the same character for "one" and "l,"which lets me see numeric
ratios rather than price per liter.
I can imagine the "fun" of explaining the Imperial system of measures to
someone who is only familiar with the metric system, although the statute
mile should be about the simplest to explain having been set by Parliment in
1592 as 5280 feet and, to my knowledge, the Imperial system simply adopted
the foot, yard and mile that already existed. Great Britian (1966?) and the
U.S. (1957) both adopted the international foot of 30.48 centimeters, so a
modern statute mile is just over 1.6 kilometers. At least your son doesn't
have the problem of having to convert speedometer, odometer and roadsign
mileages back and forth. The ratio of 5 miles/8 kilometers is burned into
my brain from running around Europe in and on vehicles with U.S. gauges
before they started dual marking.
If your son needs to chase down any other measurements, I recommend starting
with Russ Rowlett's, which is about the single best compendium on units of
measure on the web. He doesn't have everything there, but it is a good
place to start. http://www.unc.edu/~rowlett/units/index.html
