Liaison: CODATA Task Group on Fundamental Physical Constants (CODATA-TGFC)
Links between the BIPM and the CODATA-TGFC
- The CODATA-TGFC participates in the CCU.
- The BIPM hosts the CODATA-TGFC portal on the BIPM website, and regularly hosts CODATA-TGFC meetings.
- Dr Terry Quinn, former Director of the BIPM is a member of the CODATA-TGFC.
The mission of the Committee on Data (CODATA) 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 BIPM and the CODATA-TGFC cooperate to ensure consistency between the values of the fundamental constants and the SI units that depend on them. The primary output of the TGFC is the multivariate least-squares adjustment (LSA) of the values of the fundamental constants of nature, currently produced on a four-yearly cycle.
