Microcandela quick reference
| Microcandela | Candela | Millicandela | Kilocandela |
|---|---|---|---|
| 1 µcd | = 0.000001 cd | = 0.001 mcd | = 1e-9 kcd |
| 10 µcd | = 0.00001 cd | = 0.01 mcd | = 1e-8 kcd |
| 100 µcd | = 0.0001 cd | = 0.1 mcd | = 1e-7 kcd |
| 1000 µcd | = 0.001 cd | = 1 mcd | = 0.000001 kcd |
Where the microcandela fits
The next larger luminous intensity unit is the millicandela (mcd). 1 µcd = 0.001 mcd, and 1 mcd = 1000 µcd.
