lumen/square foot/steradian to watt/sq. cm/steradian (at 555 nm)
Please provide values below to convert lumen/square foot/steradian to watt/sq. cm/steradian (at 555 nm), or change ↔.
lumen/square foot/steradian
Definition: A unit of luminance, describing luminous flux per unit area (square foot) and solid angle (steradian).
Historyandorigin: Similar to other lumen-based units but using square feet as the area measurement, common in non-metric systems.
CurrentUse: Frequently used in the United States for describing the brightness of projectors, displays, or light sources in various lighting applications.
funfact: This unit is often seen in film and television lighting setups, where high-intensity focused light is required.
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 lumen/square foot/steradian to watt/sq. cm/steradian (at 555 nm)
1 lumen/square foot/steradian = 0.000001576 watt/sq. cm/steradian (at 555 nm)
1 watt/sq. cm/steradian (at 555 nm) = 634527.7632 lumen/square foot/steradian
we use cross multiplication method
lumen/square foot/steradian → 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
