International Bureau of Weights and Measures

The International Bureau of Weights and Measures (French: Bureau international des poids et mesures) is an intergovernmental organisation that was established by the Metre Convention, through which member states act together on matters related to measurement science and measurement standards (i.e. the International System of Units). The organisation is commonly referred to by its French initialism, BIPM. The BIPM's secretariat and formal meetings are housed in the organisation's headquarters in Saint-Cloud, France. The BIPM is supervised by the International Committee for Weights and Measures (French: Comité international des poids et mesures, CIPM), a directorate of eighteen members that meet normally biannually, which is in turn overseen by the General Conference on Weights and Measures (French: Conférence générale des poids et mesures, CGPM) that meets in Paris usually once every four years, consisting of delegates of the governments of the Member States and observers from the Associates of the CGPM. These organs are also commonly referred to by their French initialisms.
