Summary:The impending redefinition of the International System of Units (SI) allows realization of the kilogram using electrical metrology. It can be shown that electrical metrology can also be used to scale mass using electrostatic forces. An approach to mass metrology at the milligram scale using an Electrostatic Force Balance (EFB) is described. The relative uncertainty in EFB mass measurements is found to be substantially lower than those obtained with the current method based on subdivision of the artifact kilogram.
