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.

Centimeter-Candle
cm*c
Definition
The Centimeter-Candle is a unit of illuminance equal to 10,000 lux, representing the illuminance produced by a standard candle at a distance of one centimeter. It is a larger unit used for measuring very high levels of illumination, such as those found in bright light sources or concentrated lighting.
History/Origin
Developed as part of the CGS (centimeter-gram-second) system of units, where smaller base units were commonly used. The centimeter-candle provided a convenient way to express high illumination values without using very large numbers in the metric system.
Current Use
Less common in modern practice but may still be encountered in specialized applications or older technical literature. It provides a practical scale for measuring very bright light sources or concentrated illumination in research and industrial applications.
