I am with you on 9/10ths of this. It is especially confusing to grow up in Canada, where we try desperately to hang on to the metric system (so you learn to measure everything in centimeters, which are stupid) whilst being inundated with American t.v. shows, movies, etc. (where everything is measured in inches and feet and you have no idea what the fuck's going on). I can't really estimate what an inch looks like because I never really learned, and I can never remember how big a centimeter is because, like I said, they're dumb.
However, in terms of temperature measurement, celsius beats fahrenheit any day of the week. Fahrenheit has all these weirdly high numbers and you can never tell what's going on, but celsius just tells it like it is: 0 is freezing, 15 is springish, 21 is room temperature, 30 is a heatwave. For winter, you just flip it around: -15 is cold but not unbearable, -21 is you only leave the house to walk the dog or save your dying grandmother, and if it's -30 you're screwed (AND you probably live in Winnipeg, so worse luck anyway). With fahrenheit there's no reliability like that.
Not that I have opinions about this or anything.
