But it pretty much boils down to whatever you are used to.

Yeah, you've got that right. I grew up using Imperial measurements but also learned the metric system. I think, besides my familiarity with the former, I have a resentment for having metric foisted upon us by the government. Their arguement was that the rest of the world was going metric, and that we needed to change in order to not be left behind. Overlooked was the fact that our largest trading partner, the U.S., didn't seem too interested in switching. So what we ended-up with was a bastardised system that's neither metric nor Imperial, but a mix of both with a large dose of Americanisation thrown in. Nothing against my American friends, but if we were to have a mixed system, I would have preferred our original Canadian (Imperial) content.
In our household, the temperatures are Fahrenheit, our cars get so many miles per gallon (Imperial of course), their power is measured as horsepower and foot/pounds of torque, and we know that if you give someone an inch, they'll take a mile.
