Luminosity Converter
Convert between candela, lumen, lux, and watt (at 555nm) with configurable solid angle, area, and distance parameters.
How to Use Luminosity Converter
The Luminosity Converter helps you convert between photometric units: candela (luminous intensity), lumen (luminous flux), lux (illuminance), and watt (radiant power at 555nm peak sensitivity). Since these units measure different aspects of light, the conversion requires additional parameters like solid angle (steradians), area (m²), and distance (m). Enter your value, select source and target units, adjust the parameters as needed, and click Convert. Uses the standard luminous efficacy of 683 lm/W at 555nm. Essential for lighting designers, photographers, and engineers.
