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 Although it is not commonly used in modern applications, the phot provides a historical reference point for high-intensity lighting measurements, particularly in scientific research and specialized fields.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

Nit (nt): Common Term for Display Brightness

The nit is a non-SI unit of luminance, equivalent to one candela per square meter (cd/m²). It is widely used in the electronics and display industries to describe the brightness of screens and monitors. Higher nit values indicate brighter displays, which are essential for visibility in various lighting conditions.

Understanding nits is important for consumers and professionals when selecting display devices, as it directly affects viewing comfort and image clarity. For instance, outdoor displays require higher nit levels to remain visible under sunlight, while indoor screens can operate effectively at lower brightness levels. Evaluating nit specifications ensures that displays meet the intended usage requirements.
