Funny, I'm in the US, and I moved around a ton in primary school days (I went to 6 schools from K-5). I managed to never get instruction on the 'US' system of measure. I have no idea how many feet are in a mile, how many quarts in a gallon, cups in a quart, etc. I did manage to hit each school districts 'metric' year...6 times in a row. So I know the SI system like the back of my hand - it's kind of awkward really.
