Illumination Converter

Convert illumination units such as lux, meter-candle, foot-candle, phot, lumen per square meter, nox, and watt per square centimeter at 555 nm.

About this converter

Illumination, or illuminance, measures luminous flux arriving on a surface. It includes SI, foot-candle, lumen-per-area, historical, and 555 nm radiometric-equivalent units.

The base unit for this converter is lux, which lets us map each unit into one consistent formula layer before converting to the target unit.
