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.

Foot-Lambert

fL

Definition

The Foot-Lambert is an imperial unit of luminance equal to 3.4262590996 candela per square meter. It is commonly used in display technology and lighting applications in countries that employ imperial measurement systems.

History/Origin

This unit was developed as an imperial equivalent to the lambert, using square feet as the area unit. It provides a practical way to measure luminance in contexts where imperial units are standard, particularly in display technology and lighting applications.

Current Use

Widely used in display technology, particularly in the United States, for specifying monitor brightness, television luminance, and other display characteristics. Common in consumer electronics specifications and lighting applications where imperial units are standard.
