Uhhh, yeah...... about that. You see, America is (for whatever reason) kind of behind the times on this whole "proper weights and measures" thingy the rest of the world seems to have adopted.
I don't know why. But that's the way it is.
Easier number to remember:
Standard unit of distance: 100 or 12
Water freezes at: 0 or 32
Basic unit of weight: 1,000 or 16
Totally makes perfect sense to stick with 12, 32 and 16 amirite?
