About the units
Candela per square meter (cd/m²)
The SI unit of luminance, commonly called the nit.
Foot-lambert (fL)
(1/π) cd/ft², about 3.426 cd/m². Cinema screens are specified around 14–16 fL. One foot-lambert equals 3.4262591 nits (cd/m²).
Frequently asked questions
How many foot-lamberts are in one candela per square meter?
There are 0.291863508 foot-lamberts in one candela per square meter, and this value is exact by definition.
How do I convert nits to foot-lamberts?
Multiply the number of nits by 0.291863508. For example, 10 cd/m² × 0.291863508 = 2.91863508 fL.
How many nits are in one foot-lambert?
