Watt/Sq. cm/Steradian (at 555 nm)

The watt per square centimetre per steradian at 555 nm is a unit of radiance at the wavelength of peak human visual sensitivity. The conversion factor (683 lm/W × 10⁴) links radiant intensity to luminance at 555 nm wavelength. 


Candela/Square Meter

The candela per square metre (cd/m²) is the SI unit of luminance, measuring the luminous intensity per unit area of light travelling in a given direction. It is also known as the nit. It is used to characterize the brightness of display screens and other light sources.
