I moved to Canada from Australia 5 years ago and was dumbfounded by the amount of American measurement still in use. It's been an interesting exercise for my ageing brain to figure out how to do math with fractions of an inch etc. I'm also baffled by the number of people using American date format!

We're trying though - I'm installing new flooring in my house and the size written on the box is 7.5" x 48" x 10mm - that gave me a chuckle.

I had hoped that the current discontent with the US would prompt more people to cringe at using their measurement system, but nobody seems to see the connection.
