Candela per Square Foot
cd/ft²
Definition
The Candela per Square Foot is an imperial unit of luminance, representing the luminous intensity per unit area using the square foot as the area unit. It is commonly used in countries that employ imperial measurement systems for lighting applications.
History/Origin
Developed as part of the imperial system of measurements, this unit provides a practical way to measure surface brightness in contexts where square feet are the standard area unit. It bridges the gap between metric and imperial systems in lighting applications.
Current Use
Used in lighting design and engineering in countries using imperial units, particularly in the United States. Common in architectural lighting, display specifications, and lighting calculations where square footage is the standard area measurement.

Kilocandela per Square Meter
kcd/m²
Definition
The Kilocandela per Square Meter is a metric unit of luminance, equal to 1,000 candela per square meter. It provides a convenient way to express high luminance values without using very large numbers, making calculations and specifications more manageable.
History/Origin
This unit was introduced as a practical alternative to the base SI unit when dealing with high-luminance applications. The kilo- prefix makes it easier to work with bright light sources and high-intensity displays where the base unit would result in large numbers.
Current Use
Widely used in professional lighting, display technology, and photometry for measuring bright light sources. Common in LED displays, high-intensity lighting systems, and applications requiring precise control of very bright light output.
