Metric system

A metric system is a system of units for measurement developed in late 18th century France with decimal multipliers. In the early metric system there were two fundamental or base units, the metre and the kilogram, for length and mass. Other units were derived from these two fundamental units.

Multiples and submultiples of metric units are related by powers of ten; the names for these are formed with prefixes. This relationship is compatible with the decimal system of numbers and it contributes greatly to the convenience of metric units.

As the result of scientific progress, refinements, and different choices of base units, there have been a number attempts at creating metric systems. The modern (modern meaning post-1960) metric system is now widely used throughout the world and is called the International System of Units (SI).
