Candela/Square Metre

The candela per square metre (cd/m²) is the SI unit of luminance, measuring the luminous intensity per unit area of light travelling in a given direction. It is also known as the nit. It is used to characterise the brightness of display screens and other light sources. 


Foot-Lambert

The foot-lambert (fL) is an imperial unit of luminance equal to 1/π candela per square foot, or approximately 3.4263 candelas per square metre. It is used in cinema and theatre projector specifications in North America, where it indicates screen brightness.
