LuminosityIntensityMeasure | rangeSubclass | SubtractionFn | A FunctionQuantity is a Function that maps from one or more instances of ConstantQuantity to another instance of ConstantQuantity. For example, the velocity of a particle would be represented by a FunctionQuantity mapping values of time (which are ConstantQuantities) to values of distance (also ConstantQuantities). Note that all instances of FunctionQuantity are Functions with a fixed arity. Note too that all elements of the range of a FunctionQuantity have the same physical dimension as the FunctionQuantity itself | (<=> | domainSubclass | FunctionQuantity | |

Candela | rangeSubclass | MeasureFn | SI LuminosityIntensityMeasure. Symbol: cd. It is one of the base units in SI, and it is currently defined as follows: the Candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540*10^12 Hertz and that has a radiant intensity in that direction of 1/683 Watt per Steradian | (=> | domainSubclass | SystemeInternationalUnit |
