  A milestone revision of the International System of Units (SI) was made at
the 26th General Conference on Weights and Measures that four of the seven SI
base units, i.e. kilogram, ampere, kelvin, and mole, are redefined by
fundamental physical constants of nature. The SI base unit founding the
electrical measurement activities, i.e. ampere, is defined by fixing the
numerical value of the elementary charge to $e=1.602\,176\,634\times10^{-19}$C.
For electrical measurement, several major adjustments, mostly positive, are
involved in this SI revision. In this paper, the main impacts of the new SI for
electrical measurement activities are surveyed under the new framework.
