Abstract :
The Conference on Precision Electromagnetic Measurements (CPEM) brings together metrologists from all over the world to discuss improving measurement accuracy. Such is the status of CPEM that the participants often, consciously or unconsciously, endeavour to present their most significant discoveries and technical advances there. CPEM not only addresses problems of international uniformity of electrical and magnetic SI units, standards and measurements but also allows discussions of physical constants measurements, which are the base of these units. These discussions now include non-electrical constants such as the Boltzmann constant for the entirely new thermodynamic temperature scale. Also presented were measurements of ancillary quantities such as the local gravitational acceleration needed to link electrical SI units with the mechanical ones.
