Converting from Candela per Square Foot (cd/ft²) to Foot-lambert (fL) | Luminance

What is Candela per Square Foot (cd/ft²)

Candela per Square Foot (cd/ft²) is a unit of luminance that measures the intensity of light emitted from a surface in a specific direction. It is commonly used in lighting design and engineering to quantify the brightness of a light source.

What is Foot-lambert (fL)

Foot-lambert (fL) is another unit of luminance that measures the brightness or luminance of a surface, typically used in the field of film and photography. It indicates the amount of light reflected off or emitted from a surface.
