How to Convert Centimeter-Candle to Watt per Square Centimeter (at 555 nm)

Conversion Formula

1 cm*c = 0.001 W/cm² (at 555 nm)
1 W/cm² (at 555 nm) = 683 cm*c

Example

Convert 15 cm*c to W/cm² (at 555 nm):

15 cm*c = 15 × 0.001 W/cm² (at 555 nm) = 0.022 W/cm² (at 555 nm)

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.

Watt per Square Centimeter (at 555 nm)

W/cm² (at 555 nm)

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.
