7.5 US gallons / cubic foot, 6.25 British imperial gallons / cubic foot.


historically speaking, why is that? The Brits invented the gallon, it
conveniently weighs 10 pounds if it's water, and you Americans go ahead and
change it. What's up with that? You probably just wanted to go around
getting lousy gas mileage, or was it that you wanted to be able to carry
less weight when Ma sent you to the well to get a few gallns of water?

Inquiring minds want to know!
