CODATA Task Group on Fundamental Constants

The purpose of the CODATA Task Group on Fundamental Constants (TGFC) is "to periodically provide the scientific and technological communities with a self-consistent set of internationally recommended values of the basic constants and conversion factors of physics and chemistry based on all of the relevant data available at a given point in time."

The CODATA-TGFC is not constituted under the auspices of the BIPM, but because of the close linkage between the SI units and fundamental constants, it enjoys a close relationship with the CCU and the BIPM; this portal, created as a working website for the Task Group, is an example.

The public section of this website provides information about the activities of the Task Group on Fundamental Constants including meeting dates, meeting minutes, and membership.

CODATA internationally recommended values of the Fundamental Physical Constants (2014 LSA)

The most recent meeting of the TGFC took place on 4 September 2017 at the BIPM.
