The Foot-candles to Lux Calculator is an essential tool for professionals and enthusiasts in the lighting industry, enabling quick and accurate conversions between foot-candles (fc) and lux (lx), the two primary units of illuminance measurement. Foot-candles, predominantly used in the United States, measure the amount of light that falls on a surface within one square foot, while lux, the internationally recognized unit, measures light per square meter. The conversion is straightforward: 1 foot-candle equals approximately 10.7639 lux. This calculator simplifies the process, allowing users to input a value in either unit and instantly receive the equivalent in the other, ensuring precise lighting assessments for various applications.
