| Zusammenfassung | The discussion in this document is expected to be relevant to the values of the constants resulting from the special CODATA adjustment to be carried out in the summer of 2017 that will determine the exact numerical values of h, e, k, and NA to be used to define the revised SI and to be adopted by the 26th CGPM, here called for simplicity the “new” SI. Four of the seven exactly known defining constants of the present or “old” SI will become inexactly known constants in the new SI and must be determined experimentally. They are the mass of the international prototype of the kilogram, the magnetic constant, the triple point of water and the molar mass of the carbon. |
