Illuminance Converter
Light Level Units
Convert illuminance between lux, foot-candles, and phot.
Understanding Illuminance Conversion
1. What This Calculator Measures
Illuminance conversion compares light falling on a surface in different units.
2. How the Calculation Works
The converter changes the input to lux first, then converts lux to the requested target unit.
3. Formula or Rule Used
result = input x source illuminance factor / target illuminance factor.
