US Gallons and pint aren't quite as big as the ones over here. But their linear measurements are the same.

I've never yet met an American who thinks in terms of litres and kilometres (or "liters" and "kilometers" for that matter) and so forth. I'm sure there are some.

This little u-turn is very welcome. The unfair thing has been that big supermarkets have been blithely using imperial weights and measures much of the time, and no one has come down on them, it's just been the market traders. (For example if at the cheese counter in Sainsburys you say "I'll have a half of that" they never give you half a kilo, or even ask.)
