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.

Stilb

sb

Definition

The Stilb is a CGS unit of luminance, equal to 10,000 candela per square meter. It was part of the centimeter-gram-second system and is still used in some specialized applications, particularly in older scientific literature and certain technical contexts.

History/Origin

The stilb was originally defined in the CGS system as a unit of luminance, named after the Greek word for brightness. It was widely used in early photometry and lighting science before the adoption of SI units became standard in most applications.

Current Use

Still used in some specialized scientific applications, particularly in older technical specifications and certain branches of photometry. While largely replaced by SI units, it occasionally appears in historical contexts and specialized measurement systems.
