Luminosity Converter
Convert between different luminosity and illuminance units including candela, lumen, lux, foot-candle, and nit. Accurate conversions for lighting calculations.
Note: Direct conversions are only possible between units of the same type. For example, lux ↔ foot-candle (illuminance), but converting between different types (like candela to lumen) requires additional parameters like distance or area.
Unit Types:
- Candela (cd): Luminous intensity - light emitted in a direction
- Lumen (lm): Luminous flux - total light output
- Lux (lx): Illuminance - light falling on a surface
- Foot-candle (fc): Illuminance - imperial unit (1 fc ≈ 10.764 lx)
- Nit (nt): Luminance - light reflected/emitted from a surface
About Luminosity Converter
A comprehensive luminosity converter that handles conversions between various light measurement units including luminous intensity (candela), luminous flux (lumen), illuminance (lux, foot-candle), and luminance (nit). Essential for lighting design, photography, and engineering applications with precise conversion formulas.
Why use a Luminosity Converter?
Critical for lighting designers, photographers, engineers, and researchers who work with different light measurement standards. Prevents calculation errors in lighting projects, photography setups, and scientific measurements while supporting both professional and educational luminosity conversion needs.
