Units are extremely important in the study of science. Without them, a number is just a number without any meaning. The Système international d’unités (SI system) is a standard that simplifies international scientific communication. This system comprises seven base quantities and 16 prefixes that designate amount.

The SI or International System of units has been established for many years and it forms the basis of most of the measurements that are used globally. The International System of Units is officially termed "Système International d'Unités" and it was established in 1960 by the 11th General Conference on Weights and Measures (CGPM).

Det bygger på det metriske målesystem (fra meterkonvensjonen av 20. mai 1875) og er en videreføring av dette. The International System Of Units (SI) is the metric system that is used universally as a standard for measurements. SI units play a vital role in scientific and technological research and development. It is made up of 7 base units which are used for defining 22 derived units.
