measurement system: The metric system of measurement. For a time, the international prototype metre and kilogram were based, for convenience, on the archive standards rather than directly on actual measurement of Earth.
The basic units of the metric system define length (meter), mass (kilogram), and time (second). The chief advantage of the metric system is that it is based on standards that have been accepted by international agreement, and it therefore provides a common basis for all scientific measurements.
