The organisation is usually referred to by its French initialism, BIPM. The BIPM reports to the International Committee for Weights and Measures ( French : Comité international des poids et mesures, CIPM ), which is in turn overseen by periodic meetings of the General Conference on Weights and Measures ( French : Conférence générale des poids et mesures, CGPM ). These organizations are also commonly referred to by their French initialisms.

It is based at the Pavillon de Breteuil in Sèvres, France, a 4.35 ha ( 10.7 - acre ) site ( originally 2.52 ha ( 6.2 acres ) ) granted to the Bureau by the French Government in 1876, where it enjoys extraterritorial status, a status that was clarified by the French decree No 70 - 820 of 9 September 1970. Function Under the authority of the Metric Convention, the BIPM helps to ensure uniformity of SI weights and measures around the world. It does so through a series of consultative committees, whose members are the national metrology laboratories of the Convention 's member states, and through its own laboratory work. The BIPM carries out measurement - related research. It takes part in and organises international comparisons of national measurement standards and performs calibrations for member states. The BIPM has an important role in maintaining accurate worldwide time of day. It combines, analyses, and averages the official atomic time standards of member nations around the world to create a single, official Coordinated Universal Time ( UTC ). The BIPM is also the keeper of the international prototype of the kilogram.
