The Role of Fundamental Constants in the International System of Units (SI): Present and Future

Published

Author(s)

Barry N. Taylor, Peter J. Mohr

Abstract

This paper addresses the role of fundamental constants in (1) the current definitions of the base units; (2) practical representations of SI electric units and the consistency of those representations with the SI as deduced from the 1998 CODATA recommended values of the constants; and (3) redefinition of the kilogram and the impact on realizations of SI electric units of a newly proposed definition that fixes the value of the Planck constant h.
