Abstract

The purpose of this note is to make a brief analysis of the physical principles upon which two methods for relating the mass of an object to fundamental physical constants are based. The two methods are, namely, the watt balance method, and a still untested experimental technique based upon a superconductor electromechanical oscillator. We show that both these methods are governed by similar equations.
