Description

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 Although it is not commonly used in modern applications, the phot provides a historical reference point for high-intensity lighting measurements, particularly in scientific research and specialized fields.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.

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.
