lumen/sq. meter/steradian to watt/sq. cm/steradian (at 555 nm)
Please provide values below to convert lumen/sq. meter/steradian to watt/sq. cm/steradian (at 555 nm), or change ↔.
lumen/sq. meter/steradian
Definition: A unit of luminance, expressing the amount of luminous flux per unit area and solid angle.
Historyandorigin: This combines the lumen (a unit of luminous flux) with square meters and steradians, the units for area and solid angle, respectively.
CurrentUse: Common in photometry, particularly when measuring light emitted from a source in a specific direction or angle.
funfact: This unit is useful for describing light distribution in projectors and lighting fixtures.
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/sq. meter/steradian to watt/sq. cm/steradian (at 555 nm)
1 lumen/sq. meter/steradian = 1.464128843E-7 watt/sq. cm/steradian (at 555 nm)
1 watt/sq. cm/steradian (at 555 nm) = 6830000 lumen/sq. meter/steradian
we use cross multiplication method
lumen/sq. meter/steradian → watt/sq. cm/steradian (at 555 nm)
1 → 1.464128843E-7
1.5 → ?( suppose x)
=>1.5*1.464128843E-7=1*x
by simplifying
x=2.196193265E-7
