The physical quantity corresponding to
Concept introduction:
Metric system is a measurement system which has units of meter, liter, and gram as the units for measuring length, volume and mass. Adoption of the metric system as a universal system of measurement has been resisted by several countries. In science, measurements are regularly recorded in metric units. SI system is an extension of the metric system and has seven base units.
