Resolution 2 of the 16th CGPM (1979)

Realization of electrical units

The 16th Conférence Générale des Poids et Mesures (CGPM),


  • the importance for all applications of electrical measurements of more accurate realizations of the SI units, in particular the volt and the ampere,
  • the recent improvement in these realizations both by direct methods and by indirect methods through the determination of physical constants,
  • the divergences which remain between the results given by these different methods,
  • the need to be able to compare independent realizations among themselves to elucidate the origin of these divergences,
  • the improvement in accuracy that will be obtained as soon as a better coherence permits the establishment of more accurate values for the different realizations of these units,

recommends the continuation and intensifying of research on both the direct realization of electrical units and there indirect realization through the determination of physical constants.
