Luke Skywalker: Yes, this argument about the superiority of the metric system goes wearing upon me. Though I am one of the few people that can multiply 16 X 12 X 5280 in my head or use a calculator, I see no reason to. Looks like a little more than 960,000, make it 1,013,760. And before you whip out how many millimeters in a kilometer to show how easy the metric system is, just how often would one need to make such a calculation in real use? Let's take something a little more practical. Exactly how much is a third of a yard? A foot? A meter? See, we usually only use three decimal points, but in the standard system a lot of fraction are eliminated because it has so many prime divisors. Even the mile can be divided evenly by 11! Which will give you 480 feet or 160 yards. Try that in your metric system.
