candela/square foot to watt/sq. cm/steradian (at 555 nm)
Please provide values below to convert candela/square foot to watt/sq. cm/steradian (at 555 nm), or change ↔.
candela/square foot
Definition: A unit of luminance representing the intensity of light emitted per square foot of surface area.
Historyandorigin: The candela unit of luminous intensity is divided by the area unit of square feet, which is common in non-metric systems.
CurrentUse: Commonly used in the United States for specifying the brightness of surfaces in various lighting applications.
funfact: It's used in measuring the brightness of illuminated surfaces like office walls or street signs.
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 candela/square foot to watt/sq. cm/steradian (at 555 nm)
1 candela/square foot = 0.000001576 watt/sq. cm/steradian (at 555 nm)
1 watt/sq. cm/steradian (at 555 nm) = 634527.7632 candela/square foot
we use cross multiplication method
candela/square foot → watt/sq. cm/steradian (at 555 nm)
1 → 0.000001576
1.5 → ?( suppose x)
=>1.5*0.000001576=1*x
by simplifying
x=0.000002364
