Units of the International System
The International System
(abbreviated SI, for Systeme International,
the French name for the system) was adopted in 1960 by the 11th General
Conference on Weights and Measures. An expanded and modified version of the
metric system, International System addresses the needs of modern science for
additional and more accurate units of measurement. The key features of the
International System are decimalization, a system of prefixes, and a standard
defined in terms of an invariable physical measure.
Base Units
The International System has base units
from which all others in the system are derived. The standards for the base
units, except for the kilogram, are defined by unchanging and reproducible
physical occurences. For example, the meter is
defined as the distance traveled by light in a vacuum in 1/299,792,458 of a
second. The standard for the kilogram is a platinum-iridium cylinder kept at
the International Bureau of Weights and Standards in

Supplementary Units
The International System uses two
supplementary units that are based on abstract geometrical concepts rather than
physical standards.

Prefixes
A multiple of a unit in the International
System is formed by adding a prefix to the name of that unit. The prefixes
change the magnitude of the unit by orders of ten from 1024 to 10-24.

Derived Units
Most of the units in the International
System are derived units, that is units defined in
terms of base units and supplementary units. Derived units can be divided into
two groups - those that have a special name and symbol, and those that do not.
