Stilb

Definition

The Stilb is a CGS unit of luminance, equal to 10,000 candela per square meter. It was part of the centimeter-gram-second system and is still used in some specialized applications, particularly in older scientific literature and certain technical contexts.

History/Origin

The stilb was originally defined in the CGS system as a unit of luminance, named after the Greek word for brightness. It was widely used in early photometry and lighting science before the adoption of SI units became standard in most applications.

Current Use

Still used in some specialized scientific applications, particularly in older technical specifications and certain branches of photometry. While largely replaced by SI units, it occasionally appears in historical contexts and specialized measurement systems.

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.
