In 1948, the General Conference on Weights and Measures (Confkrence Ginirale des Poids et Mesures, CGPM), a diplomatic conference responsible for the "international unification and development of the metric system," instructed its International Committee for Weights and Measures to develop a set of rules for the units of measurement. The "International System of Unitsn (SI) was developed under this charge, adopted by the CGPM in 1960, and accepted by all signatories to the Meter Convention in 1977.
