About Lux To Foot Candle Calculator

Converting Lux to Foot-candles is one multiplication: a single lx is 0.09290304 fc, so the amount is scaled by that factor. Reversing the direction divides by the same factor. The factor is an exact definition rather than a rounded figure, so the result stays precise at any magnitude.
