  • According to Wikipedia — Kelvin (Usage conventions) — prior to the 13th General Conference on Weights and Measures (CGPM) in 1967–1968, the unit kelvin was called a "degree", the same as with the other temperature scales at the time.

  • In order to define the unit of time more precisely, the 11th General Conference on Weights and Measures (CGPM) (1960) adopted a definition given by the International Astronomical Union which was based on the tropical year.

  • Considering that a very precise definition of the unit of time is indispensable for the International System, the 13th CGPM (1967) decided to replace the definition of the second by the following (affirmed by the International Committee for Weights and Measures (CIPM) in 1997 that this definition refers to a cesium atom in its ground state at a temperature of 0 K):

  • After the revision of the Meter Convention by the 6th CGPM in 1921, which extended the scope and responsibilities of the BIPM to other fields in physics, and the subsequent creation of the CCE (now CCEM) by the 7th CGPM in 1927, the Giorgi proposal was thoroughly discussed by the IEC and the IUPAP and other international organizations.

  • Following an international inquiry by the BIPM, which began in 1948, the 10th CGPM, in 1954, approved the introduction of the ampere, the kelvin and the candela as base units, respectively, for electric current, thermodynamic temperature and luminous intensity.
