Millilux quick reference
| Millilux | Lux | Foot-candle | Kilolux |
|---|---|---|---|
| 1 mlx | = 0.001 lx | = 0.00009290304 fc | = 0.000001 klx |
| 10 mlx | = 0.01 lx | = 0.0009290304 fc | = 0.00001 klx |
| 100 mlx | = 0.1 lx | = 0.009290304 fc | = 0.0001 klx |
| 1000 mlx | = 1 lx | = 0.09290304 fc | = 0.001 klx |
