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.

Phot (ph): CGS Unit of Illuminance

The phot is a unit of illuminance in the centimeter-gram-second (CGS) system, where one phot equals 10,000 lux. Although it is not commonly used in modern applications, the phot provides a historical reference point for high-intensity lighting measurements, particularly in scientific research and specialized fields.

While the SI unit lux has largely supplanted the phot, familiarity with this unit can be beneficial when interpreting older scientific literature or working within specific contexts where CGS units are still in use. Recognizing the conversion between phot and lux ensures accurate understanding and communication of illuminance values.
