Description / Abstract:

This standard gives guidance for application of The International System of Units (the modernized metric system) developed and maintained by the General Conference on Weights and Measures (abbreviated CGPM from the official French name Conférence Générale des Poids et Mesures). The name International System of Units and the international abbreviation SI2 were adopted by the 11th CGPM in 1960.

Information is included on SI, a limited list of non-SI units recognized for use with SI units, and a list of conversion factors from non-SI to SI units, together with general guidance on proper style and usage.

It is hoped that an understanding of the system and its characteristics, and careful use according to this standard, will help to avoid the degradation that has occurred in all older measurement systems.

2 From the French name, Le Système Intemational d‘Unités.
