The candela (symbol: cd) is the SI base unit of luminous intensity. It is the power emitted by a light source in a particular direction, weighted by the luminosity function. A common candle emits light with a luminous intensity of roughly one candela. The candela is officially defined as the luminous intensity of a source that emits monochromatic radiation of frequency 540×1012 hertz and that has a radiant intensity of 1/683 watt per steradian.
