Which units to use

Recently there was some disussion here in pow-teach about which
measurement units should be employed in our problems -- metric or U.S.
customary. It caused me to reflect on things here in the country
where I live, El Salvador.

When we buy gasoline for our cars, we purchase in 'gallons'; yet we
leave the station and drive to the next town in 'kilometers'.

When my wife buys "un litro de leche" [a liter of milk], it's really a
quart of milk, but only printed on the carton as "946 ml". [No, it
doesn't give it in "cuartos", but in metric terms.]

When you ask someone how tall he/she is, they might answer in one of
two ways: (1) ciento sesenta [one hundred sixty], the assummed unit
being centimeters, or (2) uno, sesenta [one, sixty], assuming
"meters, centimeters" (much as one assumes the phrase in the "States"
of "five, nine" to mean "5 feet, 9 inches".

There are a few other oddities, but this gives the idea that one must
be flexible and capable in both systems still.
