How to Convert Foot-candle to Millilux
- 1 fc = 10763.91042 mlx
- 1 mlx = 0.00009290304 fc
- Example: convert 15 fc to mlx: 15 fc = 15 × 10763.91042 mlx = 161458.6563 mlx
Formula
mlx = fc × 10763.91041671
Derivation from SI units:
- 1 fc = 1 lm/ft² = 1/0.09290304 lx ≈ 10.7639 lx.
- 1 mlx = 10⁻³ lx.
- 1 fc = 10.76391041671 lx ÷ 0.001 lx per mlx = 10763.91041671 mlx
Both units are defined exactly, so the factor is exact. Foot-candle definition: foot-candle; Millilux definition: millilux.
Worked examples
- A reading of 20 fc converts to 215278.2083 mlx.
20 fc × 10763.91042 = 215278.2083 mlx - A value of 75 fc is 807293.2813 mlx.
75 fc × 10763.91042 = 807293.2813 mlx
