How to Convert Kilolux to Foot-candles
To convert kilolux to foot-candles, multiply the illumination by the following conversion ratio: 92.9030401 foot-candles/kilolux.
Since one kilolux is equal to 92.9030401 foot-candles, you can use this simple formula to convert:
The illumination in foot-candles is equal to the illumination in kilolux multiplied by 92.9030401.
For example, here's how to convert 5 kilolux to foot-candles using the formula above.
How Many Foot-candles Are in a Kilolux?
There are 92.9030401 foot-candles in a kilolux, which is why we use this value in the formula above.
Our kilolux to foot-candle calculator automatically converts your illumination measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Kilolux and foot-candles are both units used to measure illumination. Keep reading to learn more about each unit.
What Is a Kilolux?
A kilolux is a unit of illumination equal to 1,000 lux (lx), the base unit for illumination. Equal to 1,000 lux (outdoor daylight benchmark). [1]
The kilolux is classified as a metric and SI-compatible unit of illumination. Kilolux can be abbreviated as klx; for example, 1 kilolux can be written as 1 klx.
In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilolux (klx) a convenient decimal multiple of the lux (lx).
In practice, kilolux (klx) are widely used across large-scale industrial, bulk, and macro-level illumination specifications within SI metric workflows, engineering documentation, and technical data sheets.
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). [2]
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.
When converting illumination between kilolux (klx) and foot-candles (fc), keep full floating-point precision (1 klx = 92.9030401 fc; 1 fc = 0.0107639 klx) during intermediate calculations and round only the final foot-candle figure to match your instrument tolerance.
