Candela per Square Inch
cd/in²
Definition
The Candela per Square Inch is an imperial unit of luminance, representing the luminous intensity per unit area using the square inch as the area unit. It is used for measuring very bright light sources and small-area displays.
History/Origin
This unit was developed for applications requiring precise measurement of small, bright light sources where square inches provide a more appropriate area reference. It is particularly useful in electronics and display technology where component sizes are measured in inches.
Current Use
Commonly used in electronics manufacturing, small display technology, and precision lighting applications. Essential for measuring LED arrays, small screens, and compact light sources where square inch measurements are standard.
