So basically for the non-metric measures, "where you are" matters. Because, hey, a Pint (ounce, gallon, pretty much whatever) abroad is pretty much not what it is back home.

And don't get me started on miles / nautical miles.

But at least now I know there are 36 Bushels to a Chaldron. If only I had a clue what a bushel is.

Bet you don't know how many rods in a furlong?
