TOWARDS A NEW DEFINITION OF THE KELVIN: WAYS TO GO

Joachim Fischer, Bernd Fellmuth, Joachim Seidel, Wolfgang Buck

Abstract

The present definition of the kelvin links the unit of temperature with a material property. It would be more consistent with the current approaches to other base units to fix the value of the Boltzmann constant <i>k</i>, in- stead. For this purpose, <i>k</i> must first be determined with distinctly lower uncertainty. This paper considers ex- perimental methods having potential to contribute to the determination of <i>k</i>.
