The Bureau interntional des poids et mesures (BIPM, sometimes referred to in English as the International Bureau of Weights and Measures) is an international organization based in Sèvres, just outside Paris, France. It was established in 1875 by the Metre Convention to conserve the new international prototypes of the metre and the kilogram and to arrange for comparison of national standards: in its modern role, it acts as an international version of a national measurement laboratory (such as the National Institute for Standards and Technology (NIST) in United States or the National Physical Laboratory in the United Kingdom).

Functions

The BIPM defines its functions as:[1]

  • establishing fundamental standards and scales for the measurement of the principal physical quantities and maintaining the international prototypes;
  • carrying out comparisons of national and international standards;
  • ensuring the coordination of corresponding measurement techniques;
  • carrying out and coordinating measurements of the fundamental physical constants relevant to these activities.
