General Conference on Weights and Measures (CGPM) November 2018

09 November 2018

Witness a historic moment; join an open session of the General Conference on Weights and Measures (CGPM) considering the revision of the SI - including redefinition of four of the base units.

The 26th General Conference on Weights and Measures (CGPM) will take place in Versailles in November 2018. At this meeting, we expect the CGPM to approve a resolution to revise the definitions of the International System of Units, the SI, which is based on the second, the metre, the kilogram, the ampere, the kelvin, the mole and the candela (the SI base units).
