JOULE INSTEAD OF KELVIN IN A SET OF BASE UNITS

Waldemar Nawrocki

Abstract

The joule is proposed to replace the kelvin in the set of SI base units. Arguments in favour of such replacement are presented, including improved standard accuracy and unit system coherence. The joule is also proposed to be added to the quantum metrological triangle (which couples the volt, the ampere and the hertz) to transform the latter into a system called quantum metrological pyramid, that would couple four units rather than three, and allow comparison of the respective standards.
