Millicandela quick reference
| Millicandela | Candela | Microcandela | Kilocandela |
|---|---|---|---|
| 1 mcd | = 0.001 cd | = 1000 µcd | = 0.000001 kcd |
| 10 mcd | = 0.01 cd | = 10000 µcd | = 0.00001 kcd |
| 100 mcd | = 0.1 cd | = 100000 µcd | = 0.0001 kcd |
| 1000 mcd | = 1 cd | = 1000000 µcd | = 0.001 kcd |
Where the millicandela fits
The next smaller luminous intensity unit is the microcandela (µcd). 1 mcd = 1000 µcd, and 1 µcd = 0.001 mcd.
The next larger luminous intensity unit is the candela (cd). 1 mcd = 0.001 cd, and 1 cd = 1000 mcd.
