Table P3 Common photometric units
luminous flux
lumens
luminous intensity (I)
candela = lumens/steradian
illuminance (E)
lux = lumens/m2
footcandle = lumens/ft2
luminance (L)
candela/m2
candela/ft2

millilambert
1 footlambert (fL) = 3.426 cd/m2
1 lambert = 3183 cd/m2
1 millilambert = 3.183 cd/m2
1 candela/m2 = 0.2919 fL
1 candela/ft2 = 3.142 fL
