Candela per Square Meter

cd/m²

Definition

The Candela per Square Meter is the SI derived unit of luminance, representing the luminous intensity per unit area of light traveling in a given direction. It quantifies how much light is emitted or reflected from a surface area.

History/Origin

Derived from the SI base units of luminous intensity (candela) and area (square meter), this unit was established as part of the modern metric system. It provides a standardized way to measure surface brightness and is fundamental to photometry and lighting design.

Current Use

Widely used in lighting engineering, display technology, and photometry for measuring screen brightness, surface illumination, and light output. Essential for designing lighting systems, evaluating display performance, and ensuring proper illumination levels in various applications.

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.
