Progress in the Realization of Electrical Units at the Board for Standardization, Metrology, and Goods Testing (ASMW)

This paper reports on the progress that has been made particularly in the realization of the ampere by means of the method of nuclear magnetic resonance and in the determination of the gyromagnetic ratio ?'p at the ASMW in the past few years. In addition, it describes the latest results of the work aimed at realizing the ohm and the volt.
