How to Convert Luminous Intensity Units
Luminous intensity is the light power emitted by a source in a particular direction, weighted for human eye sensitivity. It is one of the seven SI base units, the candela (cd); LED datasheets often use millicandela.
Every unit on this page is stored as a fixed factor relative to one reference unit, the candela (cd). Converting is a two step multiply and divide:
- Multiply your value by the factor of the source unit to get the value in cd.
- Divide that result by the factor of the target unit.
