In the late 1700s, The french academy of sciences set out to make a simple and reliable measurement system.

Over the next 200 years the metric system was formed.

This system is now the International system of Unit (SI)

Because all the the SI units are expressed in multiples of 10, changing from 1 unit to another is easy.

Prefixes are used to express SI units that are longer or smaller than basic units , such as meter, liter and gram.
