CCM-mission

Mission

The CCM was set up in 1980.

Present activities concern matters related to the realization and dissemination of the mass unit following the 2018 redefinition of the kilogram in terms of the Planck constant, establishment of international equivalence between national laboratories for mass and a number of related quantities (density, pressure, force, fluid flow, viscosity, hardness, gravitational acceleration) and advice to the CIPM on these matters.
