What is the foot-lambert unit used for?

Foot-lambert is an imperial unit of luminance mainly used for specifying screen brightness in cinemas and home theaters, as well as in projection system design.

Why convert foot-lambert to lambert?

Converting to lambert enables comparison and analysis in optical engineering and photographic contexts where lambert, a non-SI CGS unit, is commonly used.

Is lambert widely used in modern luminance measurements?

Lambert is less common in current standards compared to SI units like candela per square meter, but remains relevant in certain historical or specialized fields.
