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.
