The stilb (symbol: sb) is a unit of measurement for illuminance, representing the luminous intensity per unit area. It is primarily used in the field of photometry to quantify how much light is emitted or received by a surface. One stilb is equivalent to one lumen per square meter, making it an essential unit for understanding lighting conditions in various environments.
The stilb is part of the International System of Units (SI) and is standardized to ensure consistency across scientific and engineering applications. This standardization allows for accurate comparisons and calculations in lighting design, photography, and other fields where light measurement is critical.
The concept of measuring light dates back to the early 20th century, with the stilb being introduced as a part of the metric system. Over time, as technology advanced and the need for precise lighting measurements grew, the stilb became an integral part of photometric studies, helping professionals in various industries to optimize lighting conditions.
To convert illuminance from lumens per square meter (lm/m²) to stilbs (sb), you can use the following relationship: 1 sb = 1 lm/m²
For example, if you have a light source that emits 500 lumens over an area of 10 square meters, the illuminance in stilbs would be: 500 lm / 10 m² = 50 sb
Stilbs are commonly used in various applications, including:

The phot (symbol: ph) is a unit of illuminance that measures the amount of light received per unit area. Specifically, one phot is defined as one lumen per square centimeter. This measurement is crucial in fields such as photography, horticulture, and interior design, where understanding light levels is essential for optimal performance and aesthetics.
The phot unit is part of the CGS (centimeter-gram-second) system, which is a metric system of physical units. Although the phot is not commonly used in modern scientific literature, it serves as a historical reference point for illuminance measurement. The SI unit for illuminance is the lux, where 1 phot equals 10,000 lux.
The phot was introduced in the early 20th century as a means to quantify light levels in various environments. Over time, the need for a more standardized and universally accepted unit led to the adoption of the lux as the primary unit of illuminance in the International System of Units (SI). Despite this shift, the phot remains relevant for specific applications and historical context.
To convert illuminance from lux to phot, you can use the following formula: [ \text{Illuminance in phot} = \text{Illuminance in lux} \times 0.0001 ]
For example, if you have an illuminance level of 500 lux, the equivalent in phot would be: [ 500 \text{ lux} \times 0.0001 = 0.05 \text{ ph} ]
The phot is particularly useful in specialized fields such as:
