The BIPM's mission and role:

The mission of the BIPM is to ensure and promote the global comparability of measurements, including providing a coherent international system of units for:

  • Scientific discovery and innovation,
  • Industrial manufacturing and international trade,
  • Sustaining the quality of life and the global environment.

The unique role of the BIPM enables it to achieve its mission by developing the technical and organizational infrastructure of the International System of Units (SI) as the basis for the world-wide traceability of measurement results. This is achieved both through technical activities in its laboratories and through international coordination.
