How to Convert Kilolux to Millilux
- 1 klx = 1000000 mlx
- 1 mlx = 0.000001 klx
- Example: convert 15 klx to mlx: 15 klx = 15 × 1000000 mlx = 15000000 mlx
Formula
mlx = klx × 1000000
Derivation from SI units:
- 1 klx = 10³ lx.
- 1 mlx = 10⁻³ lx.
- 1 klx = 1000 lx ÷ 0.001 lx per mlx = 1000000 mlx
Both units are defined exactly, so the factor is exact. Kilolux definition: kilolux; Millilux definition: millilux.
Worked examples
- A reading of 20 klx converts to 20000000 mlx.
20 klx × 1000000 = 20000000 mlx - A value of 75 klx is 75000000 mlx.
75 klx × 1000000 = 75000000 mlx
