Description

Footcandle (fc): Imperial Unit of Illuminance

The footcandle is a non-SI unit of illuminance used primarily in the United States. It is defined as the illuminance on a one-square-foot surface from a uniform source of light equivalent to one lumen. One footcandle equals approximately 10.764 lux. Despite the global shift towards SI units, the footcandle remains prevalent in certain industries and applications.

Understanding footcandles is important for professionals working in lighting design, architecture, and photography within regions that use imperial measurements. It allows for the assessment and specification of lighting requirements, ensuring that spaces are adequately illuminated according to established standards and practices.

Stilb (sb): CGS Unit of Luminance

The stilb is a unit of luminance in the CGS system, where one stilb equals 10,000 candelas per square meter. Although it is not commonly used in contemporary applications, the stilb serves as a historical unit for measuring high-intensity luminance, particularly in scientific research and specialized fields.

While the SI unit cd/m² has largely replaced the stilb, knowledge of this unit is useful when interpreting older scientific data or working within specific contexts that utilize CGS units. Understanding the conversion between stilb and cd/m² ensures accurate communication and analysis of luminance measurements.
