20 ounces...beer is about the same also. We (Canada) have official 16
ounce pints in the US system, and beer pints that are 12 ounces.
>A cubic foot of water weighs 62.5 lb.
I remember 62.4, but who cares? :-)
>Five and a half yards is one rod, pole or perch.
Never became familiar with those ones...fathom, chain, neither of
those as well.
>An acre is 4840 square yards; 220 yards by 22 yards.
Here it's 208 feet by 208 feet...I think.
>A mile is 63350 inches.
5280 feet, 1760 yards...something less than 1760 metres...I guess
it'll be 63350/39.37 metres? :-)
