WebApr 10, 2024 · The SI Unit of power is Watt (W). One joule of energy transferred in a second is equal to 1 watt. 1 Watt = 1 J/s = 1 kg-m 2 /s 3. As the metric system is divided into base units and derived units, when we convert joules into base units we get ( kg-m 2 /s 2). It is used to find out the conversion of watts into base units.
The lumen (symbol: lm) is the unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time, in the International System of Units (SI). Luminous flux differs from power (radiant flux) in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model (a "luminosity function") of the human eye's sensitivity to various wavelengths. One lux is one lumen per square metre.
