The luminance (Lᵥ) is the luminous flux per unit solid angle and unit source area. The SI units of the luminance are the candela per square meter.
A candela per square inch is a unit of luminance. One candela per square inch is equal to 1550.0031 candelas per square meter.
A foot-lambert is a unit of luminance. One foot-lambert is equal to 3.426 candelas per square meter.
Divide the foot-lambert value by 452.389342
candela per square inch = foot-lambert / 452.389342
Multiply the candela per square inch value by 452.389342
foot-lambert = candela per square inch x 452.389342
One candela per square inch (cd/in²) is equal to 452.389342 foot-lambert (fL)
1 candela per square inch (cd/in²) = 452.389342 foot-lambert (fL)
One foot-lambert (fL) is equal to 0.002210 candela per square inch (cd/in²)
1 foot-lambert (fL) = 0.002210 candela per square inch (cd/in²)
