I can't speak for the Yanks, but it's just a fact of life in Canada. We're officially metric, and use that system for everything except height and weight relating to people. (The government uses metric for that too; 95% of the generation that was born before metrification doesn't.) I think it might just be that it's something personal, our own statistics that are part of our identity, and we don't want to change it.Joel said:Most of you use SI units daily and yet you tell your height and weight in feets and punds? Why?!
