Bureau International des Poids et Mesures
BIPM

    (BIPM) The standards body that ensures
   world-wide uniformity of measurements and their traceability
   to the International System of Units (SI).  The BIPM is
   based in France and operates with the authority of the
   Convention of the Metre, a diplomatic treaty between fifty-one
   nations.  It operates through a series of committees, whose
   members are the national metrology laboratories of the member
   states of the convention, 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 it carries out calibrations for
   member states.
