blondel to watt/sq. cm/steradian (at 555 nm)
Please provide values below to convert blondel to watt/sq. cm/steradian (at 555 nm), or change ↔.
blondel
Definition: A unit of luminance used in older lighting systems, similar to the apostilb.
Historyandorigin: Named after the French scientist Blondel, it was used in early photometry for brightness measurements.
CurrentUse: No longer in common use, as modern units like candela and nit have replaced it in lighting measurements.
funfact: The blondel was primarily used in historical studies of lighting, particularly in public and industrial settings.
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 blondel to watt/sq. cm/steradian (at 555 nm)
1 blondel = 4.660466854E-8 watt/sq. cm/steradian (at 555 nm)
1 watt/sq. cm/steradian (at 555 nm) = 21457077.824 blondel
we use cross multiplication method
blondel → watt/sq. cm/steradian (at 555 nm)
1 → 4.660466854E-8
1.5 → ?( suppose x)
=>1.5*4.660466854E-8=1*x
by simplifying
x=6.990700282E-8
