Luminous Intensity Units & Calculator
Candela measures luminous intensity in a direction. Lumens measure luminous flux; lux measures illuminance. These quantities cannot be interchanged using a simple scale factor.
Detailed explanation & worked examples
Conversion method
Base value = input × source factor + source offset. Output = (base value − target offset) ÷ target factor. Only units from this family can be converted together.
Worked example
For the first two units below: 1 Millicandela becomes 0.00100000 Candela.
| Unit | Multiplier | Offset |
|---|---|---|
| Millicandela | 0.001 | 0 |
| Candela | 1 | 0 |
| Kilocandela | 1000 | 0 |
Candela measures luminous intensity in a direction. Lumens measure luminous flux; lux measures illuminance. These quantities cannot be interchanged using a simple scale factor.
