foot-lambert to watt/sq. cm/steradian (at 555 nm)
Please provide values below to convert foot-lambert [fL] to watt/sq. cm/steradian (at 555 nm), or change ↔.
foot-lambert [fL]
Definition: A unit of luminance in the imperial system, equal to one candela per square foot.
Historyandorigin: The foot-lambert is derived from the lambert but uses square feet as the area measurement instead of square centimeters.
CurrentUse: Commonly used in the United States, especially for older cinema and television technologies.
funfact: The foot-lambert is still used to describe screen brightness in certain vintage or legacy equipment.
watt/sq. cm/steradian (at 555 nm)
Definition: A unit of radiant flux per unit area and solid angle, specifically at the wavelength of 555 nm, which corresponds to green light.
Historyandorigin: This unit is derived from the watt, which measures radiant power, adjusted for area (square centimeters) and solid angle (steradians), with the wavelength specified for the visible spectrum.
CurrentUse: Used in scientific research to quantify the intensity of light at a specific wavelength, particularly in photonics and color science.
funfact: 555 nm is the wavelength at which the human eye is most sensitive, making it a standard reference for brightness measurements.

How to Convert foot-lambert to watt/sq. cm/steradian (at 555 nm)
1 foot-lambert [fL] = 5.016484772E-7 watt/sq. cm/steradian (at 555 nm)
1 watt/sq. cm/steradian (at 555 nm) = 1993427.7594 foot-lambert [fL]
we use cross multiplication method
foot-lambert [fL] → watt/sq. cm/steradian (at 555 nm)
1 → 5.016484772E-7
1.5 → ?( suppose x)
=>1.5*5.016484772E-7=1*x
by simplifying
x=7.524727158E-7
