Progress on the BIPM Watt Balance

A. Picard, H. Fang, M. Stock

Abstract

In view of the future redefinition of the kilogram, the BIPM has recently started work on a watt balance to link the kilogram with the Planck constant. This paper presents an overview of the existing experimental set-up as well as the essential ideas of the BIPM watt balance and reports the progress to date.
