The electromagnetic system of units is used to measure electrical quantities of electric charge, current, and voltage, within the centimeter gram second (or "CGS") metric system of units. In electromagnetic units, electric current is derived the CGS base units length, mass, and time by solving Ampere's Law (expressing the force between two parallel conducting wires) for current and setting the constant of proportionality (k_m) equal to unity. Thus, in the CGS-EMU system, electric current is derived from length, mass, and time.
The electrostatic system of units is used to measure electrical quantities of electric charge, current, and voltage within the centimeter gram second (or "CGS") metric system of units. In electrostatic units, electric charge is derived from Coulomb's Law (expressing the force exerted between two charged particles separated by a distance) by solving for electric charge and setting the constant of proportionality (k_s) equal to unity. Thus, in electrostatic units, the dimensionality of electric charge is derived from the base CGS quantities of length, mass, and time.
The ISO 80000 standards were prepared by Technical Committee ISO/TC 12, Quantities and units in co-operation with IEC/TC 25, Quantities and units.
