Mission

The Consultative Committee for the Definition of the Metre (CCDM) was set up in 1952. Its name was changed to Consultative Committee for Length by the CIPM in 1997.

Present activities concern matters related to the definition and realization of the metre, practical length and angle measurement, and advice to the CIPM in the field of length metrology.
