The metric system is easy to learn and simply to use. There are only a few basic units, and they are generally related to each other by simple factors of 10. The metric system has a single unit for weight (grams), volume (litres), and another for length (metres). Smaller and larger units can be modified with a prefix. For example, kilo means 1000 times bigger, so a kilogram is 1000 grams and a kilometer is 1000 metres.
