Kilolux quick reference
| Kilolux | Foot-candle | Lux | Millilux |
|---|---|---|---|
| 1 klx | = 92.90304 fc | = 1000 lx | = 1000000 mlx |
| 10 klx | = 929.0304 fc | = 10000 lx | = 10000000 mlx |
| 100 klx | = 9290.304 fc | = 100000 lx | = 100000000 mlx |
| 1000 klx | = 92903.04 fc | = 1000000 lx | = 1000000000 mlx |
Where the kilolux fits
The next smaller illumination unit is the foot-candle (fc). 1 klx = 92.90304 fc, and 1 fc ≈ 0.01076391042 klx.
The next larger illumination unit is the phot (ph). 1 klx = 0.1 ph, and 1 ph = 10 klx.
