NCIt definition : The International System of Units (Systeme International d'Unites, SI) is a decimal
system of weights and measures derived from and extending the metric system of units
established through the Treaty of the Meter (Convention du Metre) signed in Paris
in 1875 and currently signed by 48 nations including all the major industrialized
countries. The SI is maintained by the International Bureau of Weights and Measures
(BIPM, for Bureau International des Poids et Mesures), and is updated every few years
by an international conference, the General Conference on Weights and Measures (CGPM,
for Conference Generale des Poids et Mesures). SI has a short list of base units defined
in an absolute way without referring to any other units: the metre, the kilogram,
the second, the ampere, the kelvin, the mole, and the candela. The base units are
consistent with the part of the metric system called the MKS system.;
