Abstract
This paper addresses the role of fundamental constants in 1) the current de finitions of the SI 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) redefiniti on 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.
