It's easy, because of the proximity to the States and the fact that we still have generations in Canada that were alive PRIOR to metric who have handed it down, we're more or less raised with it. I can't speak for others, but I can pretty freely convert between the two (at least very close, I can't completely convert Celsius and Fahrenheit in my head).
But yeah, that's pretty accurate as to how everyday measurements go here. I'm trying to think of others, but I think this covers most/all of them.
