Meaning of International System in English:

International System

noun

  • 1More fully "International System of Units". A system of physical units having as base units the metre, kilogram, second, ampere, kelvin, candela, and mole, with derived units defined in terms of these by a set of prefixes indicating multiplication or division by a power of ten; abbreviated SI.

    The system is based on the metric system, but with refined definitions avoiding as far as possible reliance on a physical artefact as the defining object. Following the redefinition of the metre the only unit now relying on such a standard is the kilogram.
