The word horsepower does originate from some measure of the power of one horse :) But I concur, I'm English, so I've grown up with the metric system, but there are also some imperial stragglers around (distance, speed, etc), and I can say with out a doubt that metric is so much easier to use and understand. Eg: I have absolutely no idea how many yards there are in a mile, but I know it's 1000 meters in a kilometer.

When would you need to know how many yards there are in a mile (aside from a damn good pub quiz type question!)

I've never needed to know the amount!

But then again - who's used the pythagorus theory since leaving school? :-)
