I'm from USA. Can someone tell me the difference between the metric system and International System of Units?

As it exists today, the metric system is the SI (International unit system). The name "metric system" has (apparently) denoted several different systems throughout, the only real difference being the actual length of the base unit. The purpose of a metric is to get rid of the ambiguity between, for example inches, feet and yards. It is difficult to transfer back and forth between these different units of measure, so a single unit (the "metric" of the system) is set, and every other unit is based on a clear, easy to translate multiple. Since we use 10 as our base, it is only natural to do the same with units of measure. This way transitioning between different units requires only moving the decimal place.
