Unit Explanations
Candela Square Footcd·ft²
Source UnitThe candela square foot (cd·ft²) is a unit of measurement for luminance, which quantifies the amount of light emitted from a surface per unit area in a given direction. Specifically, it describes the intensity of light as perceived by the human eye in relation to one square foot of surface area, illuminated by a source emitting one candela. This unit is crucial for applications in lighting design, photography, and visual ergonomics, as it helps in assessing how brightly a surface appears under specific lighting conditions. The candela, the base unit of luminous intensity in the International System of Units (SI), is defined based on the light emitted by a source at a frequency of 540 × 10^12 Hz, which is perceived by the human eye as a specific brightness. Thus, the candela square foot provides a practical means of understanding luminance in everyday scenarios.
Current Use
The candela square foot is widely used in various industries related to lighting and visual ergonomics. In architectural design, it helps architects and interior designers assess how lighting will affect the aesthetics and functionality of a space. In photography, it is crucial for photographers to understand the luminance of surfaces to achieve the desired exposure levels. The entertainment industry, particularly in theater and film production, also utilizes this measurement to ensure proper lighting on stage or set environments. Additionally, in the field of automotive lighting, engineers use the candela square foot to evaluate headlight brightness and effectiveness. Countries that primarily use the imperial measurement system, such as the United States, often rely on this unit for practical applications, while it may also be referenced in international contexts where feet are commonly used. Overall, the candela square foot serves as an essential unit in assessing and communicating light levels across diverse sectors.
Fun Fact
The candela square foot is often used in the film industry to ensure proper lighting for scenes.
SkotSk
Target UnitThe skot (Sk) is a non-SI unit of luminance, which quantifies the amount of light that is emitted from a surface in a given direction per unit area. Specifically, it is defined as the luminance produced by a light source emitting one lumen per square meter. This measurement is crucial in fields such as photography, cinematography, and lighting design, where understanding the intensity of light on surfaces is essential for achieving the desired visual outcomes. The skot allows for precise control over lighting conditions and is instrumental in the study of visual perception, aiding in the evaluation of the brightness of various light sources in relation to human vision sensitivity.
Current Use
The skot is predominantly used in fields such as architectural lighting, film and television production, and photography, where accurate measurement of luminance is critical. It is especially important for lighting designers who need to ensure optimal illumination levels for aesthetic and functional purposes. In countries like the United States and members of the European Union, the skot serves as a reference point in lighting regulations and standards, helping professionals adhere to safety and efficiency guidelines. Its application extends to research institutions studying visual perception, where controlled lighting conditions are essential for experiments and observations. The skot remains a valuable tool for professionals aiming to create environments that enhance visual comfort and performance.
Fun Fact
The skot was developed to address the unique lighting needs of various industries as technology evolved.

Candela Square Foot
luminance • Non-SI
Definition
The candela square foot (cd·ft²) is a unit of measurement for luminance, which quantifies the amount of light emitted from a surface per unit area in a given direction. Specifically, it describes the intensity of light as perceived by the human eye in relation to one square foot of surface area, illuminated by a source emitting one candela. This unit is crucial for applications in lighting design, photography, and visual ergonomics, as it helps in assessing how brightly a surface appears under specific lighting conditions. The candela, the base unit of luminous intensity in the International System of Units (SI), is defined based on the light emitted by a source at a frequency of 540 × 10^12 Hz, which is perceived by the human eye as a specific brightness. Thus, the candela square foot provides a practical means of understanding luminance in everyday scenarios.
History & Origin
The concept of luminance dates back to the early 20th century when scientists began to understand light and its interaction with surfaces. The candela itself was defined in 1946 at the first General Conference on Weights and Measures (CGPM) as a measure of luminous intensity. The incorporation of surface area into this measurement led to the development of the candela square foot as a practical unit for evaluating lighting in real-world applications, particularly in contexts where the foot is a common measurement unit, such as architecture and interior design. Its adoption has allowed for a standardized way of expressing luminance in spaces measured in feet, facilitating clearer communication among professionals in various fields.
Etymology: The term 'candela' is derived from the Latin word for candle, 'candela', reflecting the unit's historical roots in candlelight as a standard for measuring luminous intensity.
