Light Unit Converters

Light Unit Converters

Convert light units for lighting design and photometry applications. These converters cover luminance, illumination, and luminous intensity measurements used in lighting design, photography, and optical engineering.

Luminance Converter

Convert between different luminance units including candelas per square meter, foot-lamberts, and nits.

Common conversions: cd/m² to fL, nits to cd/m², luminance units

Illumination Converter

Convert between different illumination units including lux, foot-candles, and lumens per square meter.

Common conversions: lux to fc, lm/m² to lux, illumination units

Luminous Intensity Converter

Convert between different luminous intensity units including candelas, candlepower, and millicandelas.

Common conversions: cd to cp, mcd to cd, luminous intensity units

About Light Unit Converters
