Definition
The Watt per Square Centimeter (at 555 nm) is a unit of spectral irradiance that can be converted to illuminance at the peak sensitivity wavelength of the human eye. It represents the radiant power per unit area at 555 nm, weighted by the luminous efficacy of radiation.
History/Origin
Developed for converting between radiometric and photometric quantities at the peak sensitivity wavelength of human vision. It provides a bridge between physical light measurements and perceived brightness, using the luminous efficacy of 683 lumens per watt at 555 nm.
Current Use
Used in optical engineering, laser technology, and display characterization where the relationship between radiant power and perceived brightness is important. It allows for precise conversion from physical measurements to photometric quantities for monochromatic light sources.

Lumen per Square Centimeter
lm/cm²
Definition
The Lumen per Square Centimeter is a unit of illuminance equal to 10,000 lux, representing the luminous flux per unit area using the centimeter as the area unit. It is used for measuring very high levels of illumination, particularly in concentrated light sources or small area applications.
History/Origin
Developed as part of the CGS system where smaller area units were commonly used. It provides a convenient way to express high illumination values without using very large numbers, particularly useful in scientific and technical applications.
Current Use
Used in specialized applications requiring measurement of very high illumination levels, such as laser technology, concentrated light sources, or scientific research involving intense light fields. It provides a practical scale for quantifying high-intensity illumination.
