(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.
