BIPM

The International Bureau of Weights and Measures is the English translation of the name of the Bureau international des poids et mesures (BIPM), a standards organisation, one of the three organisations established to maintain the International System of Units (SI) under the terms of the Convention du Mètre (Metre Convention). Note that the French name (Bureau International des Poids et Mesures) is most of the time used instead of the English translation, and that the abbreviation IBWM is not used at all.
