The International Bureau of Weights and Measures (BIPM) is an intergovernmental organization set up by the Metre Convention, and has its headquarters near Paris, France. It is financed jointly by its Member States and operates under the exclusive supervision of the CIPM.

Its mandate is to provide the basis for a single, coherent system of measurements throughout the world, traceable to the International System of Units (SI). This task takes many forms, from direct dissemination of units (as in the case of mass and time) to coordination through international comparisons of national measurement standards (as in electricity and ionizing radiation). One of the units for which the BIPM has responsibility is the mole, and metrology in chemistry is an increasing important aspect of the work of the BIPM and its 54 Member States and 32 Associated States and Economies.
