Luminance converters
Luminance measures luminous intensity emitted or reflected per projected area. This CalculatorHQ catalog contains 19 canonical units and 342 directional conversion routes in this category. Most luminance conversions are linear. CalculatorHQ converts each unit through nit and derives the target value from the two canonical scale factors. Unit names that include regional, historical, dry, liquid, survey, or standard-condition qualifiers are treated as distinct definitions.
