For example, the relationship between liter and kilogram seems
wonderfully logical until you forget to take into account just under what
precise (and largely arbitrary) conditions a kilogram and a liter of water
can be considered equivalent.

Most normal situations. What about the relationship between the gallon and
the pound? And by the way, which gallon and which pound?

For everyday purposes, one gallon of water weighs eight pounds. This
is for the standard cooking gallon, measured in a marked cup, and
pound, measured on a scale. The corrections for temperature, etc, are
smaller than the tolerance in the measurements and this is appropriate
for situations using gallons.

Always figured it as 8.3, myself. Of course, I wasn't cooking, but
doing Percolation Tests in remote sites where you hiked in with the
water. (At that point, every 0.3 counts._)

And, of course, the truly important values - 6.0#/U.S. Gal. for
100/130, 6.5 #/USGal for JP-4, and 6.7#/USGal for JP-5.
