Full name: nanocandela
Plural form: nanocandelas
Symbol: ncd
Category type: luminous intensity
Scale factor: 1.0E-9
The SI base unit for luminous intensity is the candela.
1 candela is equal to 1000000000 nanocandela.
Valid units must be of the luminous intensity type.
You can use this form to select from known units:
The SI prefix "nano" represents a factor of 10-9, or in exponential notation, 1E-9.
So 1 nanocandela = 10-9 candelas.
The definition of a candela is as follows:
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.
