How to Convert Foot-candles to Millilux
To convert foot-candles to millilux, multiply the illumination by the following conversion ratio: 10,763.9104 millilux/foot-candle.
Since one foot-candle is equal to 10,763.9104 millilux, you can use this simple formula to convert:
The illumination in millilux is equal to the illumination in foot-candles multiplied by 10,763.9104.
For example, here's how to convert 5 foot-candles to millilux using the formula above.
How Many Millilux Are in a Foot-candle?
There are 10,763.9104 millilux in a foot-candle, which is why we use this value in the formula above.
Our foot-candle to millilux calculator automatically converts your illumination measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Foot-candles and millilux are both units used to measure illumination. Keep reading to learn more about each unit.
What Is a Foot-candle?
A foot-candle is a unit of illumination equal to 10.7639104 lux (lx), the base unit for illumination. Architectural and photography lighting unit (1 lm/ft² ≈ 10.7639 lux). [1]
The foot-candle is classified as a US customary unit of illumination. Foot-candles can be abbreviated as fc; for example, 1 foot-candle can be written as 1 fc.
When working with foot-candles (fc) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, foot-candles (fc) are widely used across standard illumination applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a Millilux?
A millilux is a unit of illumination equal to 1/1,000 of a lux (0.001 lx). Low-light starlight/moonlight illuminance unit (0.001 lx). [2]
The millilux is classified as a metric and SI-compatible unit of illumination. Millilux can be abbreviated as mlx; for example, 1 millilux can be written as 1 mlx.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millilux (mlx) a convenient decimal multiple of the lux (lx).
In practice, millilux (mlx) are widely used across fine-tolerance laboratory, analytical, and micro-scale illumination measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting illumination between foot-candles (fc) and millilux (mlx), keep full floating-point precision (1 fc = 10,763.9104 mlx; 1 mlx = 0.000092903 fc) during intermediate calculations and round only the final millilux figure to match your instrument tolerance.
