The new International System, was created in response to
the problems a growing scientific
community faced in the proliferation of various
subsystems improvised to serve particular
disciplines. At the same time, it had long been
apparent that the original 18th-century standards
were not accurate to the degree required to satisfy
the 20th-century scientific world. New
definitions were required. After lengthy
discussion the 11th General Conference on Weights
and Measures, meeting in Paris (birthplace of the
metric system) in October 1960 formulated a new
International System of Units (abbreviated SI).
The CGPM is the international authority that
ensures wide dissemination of the SI and modifies
the SI as necessary to reflect the latest
advances in science and technology. For more infomation about SI, CGPM and their backgrounds, visit: Bureau International des Poids et Mesures.
