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 Although the phot is not commonly used in modern scientific literature, it serves as a historical reference point for illuminance measurement.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:

A footcandle (fc) is a unit of illuminance that quantifies the amount of light that falls on a surface. Specifically, one footcandle is defined as the illuminance produced by a uniform light source of one candela at a distance of one foot. This measurement is crucial in various fields, including photography, architecture, and horticulture, where precise lighting conditions are essential for optimal performance.
The footcandle is part of the Imperial system of measurement and is commonly used in the United States. It is standardized by the International System of Units (SI), which allows for consistent and reliable measurements across different applications. Understanding footcandles is vital for professionals who need to ensure adequate lighting in workspaces, classrooms, and public areas.
The concept of measuring light has evolved significantly since the early days of photography and film. The footcandle emerged as a practical unit in the early 20th century, providing a standardized way to discuss and measure light levels. Over time, advancements in lighting technology and a deeper understanding of human vision have led to more refined methods of measuring illuminance, including the use of lux, which is the metric equivalent of footcandles.
To illustrate how to convert footcandles to lux, consider a scenario where a room is illuminated with a light source that produces 50 footcandles. To convert this to lux, you can use the conversion factor: 1 footcandle = 10.764 lux. Therefore, 50 fc x 10.764 = 538.2 lux.
Footcandles are widely used in various industries, including:
To effectively use the footcandle tool available at Inayam's Illuminance Converter, follow these steps:
What is a footcandle? A footcandle is a unit of illuminance that measures the amount of light falling on a surface, defined as one lumen per square foot.
How do I convert footcandles to lux? To convert footcandles to lux, multiply the footcandle value by 10.764. For example, 10 fc equals 107.64 lux.
Why is footcandle important in photography? Footcandles help photographers determine the appropriate lighting conditions for capturing images, ensuring optimal exposure and clarity.
What are the recommended footcandle levels for office spaces? The recommended footcandle levels for office spaces typically range from 30 to 50 fc, depending on the tasks being performed.
Can I use the footcandle tool for outdoor lighting? Yes, the footcandle tool can be used to measure outdoor lighting conditions, helping you assess the adequacy of illumination for safety and aesthetics.
By utilizing the footcandle tool effectively, you can ensure that your lighting conditions meet the necessary standards for various applications, ultimately enhancing your projects and improving user experience. For more information and to access the tool, visit Inayam's Illuminance Converter.
