解説
The MKS system was proposed by Giovanni Giorgi in 1901 to resolve inconsistencies in CGS electromagnetic units. It uses practical units: the newton for force (kg·m/s²), the joule for energy (kg·m²/s²), and the watt for power (kg·m²/s³). SI extended MKS by adding four more base units — the ampere, kelvin, mole, and candela — creating the complete seven-unit framework still used today.
