The RNMF will be present at the International Congress of Metrology which will take place in Lyon from March 11 to 14, 2025. The CIM 2025 has a special character on the occasion of the 150th anniversary of the signature of the metre Convention.

May 20 will be the 150th anniversary of the signature of the metre Convention. This international treaty allowed the creation and dissemination of the International System of Units, the SI. In France, the RNMF laboratories are the reference laboratories for the production of measurement standards for the implementation of SI units, the maintenance of standards and the dissemination of references. The work of metrologists supports the innovations of tomorrow's world, guaranteeing the quality of monitoring of the parameters that characterize the environment, or developing methods for characterizing and evaluating quantum technologies or artificial intelligence.
This work will be presented by RNMF researchers at CIM 2025.
