## Kilogram Definition and Usage

One kilogram is equal to the mass of the platinum-iridium bar which is stored in SÃ¨vres, France. It is roughly equal to the mass of 1,000 cubic centimeters of water.

The kilogram, or kilogramme, is the SI base unit for weight, and is also a multiple of the gram. In the metric system, "kilo" is the prefix for 10^{3}. Kilograms can be abbreviated as *kg*, for example 1 kilogram can be written as 1 kg.

### Background and Origin

Originally, the kilogram was defined in 1793 as the mass equal to one cubic decimeter of water and was adopted by France as the base unit of mass. It was later adopted for use internationally, but in 1889 it was redefined as the mass equal to that of a platinum-iridium bar called the International Prototype Kilogram. It is the only unit in the international system of measures that is defined using a physical artifact.
