Well USA doesn't use the metric system because of 2 reasons. 1. They are used to using the customary system (but they use the metric system often) Example: A liter of Coca Cola. 2. Money issues. (If USA were to switch to the metric system they would have to use a lot of money to change signs and maybe even instead of putting miles in cars kilometers). By the way I think we are the only country that uses metric system all over the world.(I think some people use it in Canada but I don't know) If interested about more ask more questions and I will try to answer them as soon as possible. EDIT___________________________________________________________EDIT Most countries use the metric system. The USA is one of the few countries that doesn't use it. EDIT___________________________________________________________EDIT Those may be right answers, I don't know much. But, I DO know that we also don't use the metric system. Because, since we hated the British we didn't want to be like them. They use the metric system because it seemed easier, well, 100 cm = 1 m. And 100oC is Boiling point - things like that. Why we hated the British? That's a question for Social Studies! - A 6th grade answer from a 6th grade student! :) EDIT___________________________________________________________EDIT The FRENCH invented the metric system.
