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.
