Light & Electricity
Luminous Intensity Converter
Light sent out in one direction: candela, millicandela (LED specs) and candlepower. Lumens to candela also needs the beam angle.
That is below absolute zero (−273.15 °C), which isn’t physically possible.
1 Candela = 1,000 Millicandelas
Formula: multiply the luminous intensity value by 1,000
1 cd in every luminous intensity unit
Tap a row to convert to that unit.
How to convert luminous intensity units
Light sent out in one direction: candela, millicandela (LED specs) and candlepower. Lumens to candela also needs the beam angle. Every conversion goes through one base unit, the candela, using exact factors, so results don’t drift.
Candelas to millicandelas (cd to mcd)
To convert candelas to millicandelas, multiply by 1,000. 1 candela = 1,000 millicandelas.
| cd | mcd |
|---|---|
| 1 cd | 1,000 mcd |
| 2 cd | 2,000 mcd |
| 5 cd | 5,000 mcd |
| 10 cd | 10,000 mcd |
| 20 cd | 20,000 mcd |
| 50 cd | 50,000 mcd |
| 100 cd | 100,000 mcd |
Millicandelas to candelas (mcd to cd)
To convert millicandelas to candelas, divide by 1,000. 1 millicandela = 0.001 candelas.
| mcd | cd |
|---|---|
| 1 mcd | 0.001 cd |
| 2 mcd | 0.002 cd |
| 5 mcd | 0.005 cd |
| 10 mcd | 0.01 cd |
| 20 mcd | 0.02 cd |
| 50 mcd | 0.05 cd |
| 100 mcd | 0.1 cd |
Candlepower to candelas (cp to cd)
To convert candlepower to candelas, multiply by 1. 1 candlepower = 1 candela.
Lumens per steradian to candelas (lm/sr to cd)
To convert lumens per steradian to candelas, multiply by 1. 1 lumen per steradian = 1 candela.
