CCEM Working Group on Electrical Methods to Monitor the Stability of the Kilogram (CCEM-WGKG)
Having completed its mission, this group was closed by the CCEM in March 2019.

The CCEM-WGKG (like the CCEM-WGSI) addresses the topic of the proposed redefinition of the SI, in which the electrical quantum effects play a central role.
