1 lux equals 0.092903 foot-candles
How to convert lux to foot-candles
Illuminance is luminous flux arriving per surface area: 1 lx = 1 lm/m². Converting lux to lumens requires an area and a model of how the light is distributed.
fc = lx ÷ 10.76391042One foot-candle corresponds to 10.76391042 lux, so divide by that figure. Displayed constants may be rounded; the converter uses the stored factor before rounding the result.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
