Unit Explanations
Candela per Square Centimetercd/cm²
Source UnitThe candela square centimeter (cd/cm²) is a derived unit of luminance, defined as the luminous intensity of one candela distributed over an area of one square centimeter. It quantifies how bright a surface appears when illuminated, taking into account the human eye's sensitivity to different wavelengths of light. This unit is particularly useful in assessing the brightness of small light sources or surfaces in optical applications, as it conveys a clear sense of how much light is being emitted per unit area. The candela itself is one of the seven base SI units, representing the intensity of light emitted in a particular direction, making the cd/cm² a critical measure in fields such as photometry and lighting design.
Current Use
The candela per square centimeter is extensively used in various industries that require precise luminance measurements. In the field of display technology, manufacturers rely on cd/cm² to specify the brightness of screens, monitors, and televisions, ensuring optimal visibility under different lighting conditions. In cinematography and photography, this unit helps professionals evaluate lighting setups and ensure accurate exposure levels. The medical field utilizes cd/cm² when assessing the brightness of surgical lighting and diagnostic devices, ensuring adequate illumination during procedures. Additionally, in architectural lighting design, this unit aids in determining the effectiveness of light fixtures in illuminating spaces. Countries such as the United States, Japan, and members of the European Union primarily use the cd/cm² in both commercial and research settings to maintain consistency in luminous intensity reporting and analysis.
Fun Fact
The term 'candela' was first defined in 1948 during the 9th General Conference on Weights and Measures.
Brilbril
Target UnitThe bril is a non-SI unit of luminance, primarily used to describe the brightness of light sources as perceived by the human eye. It is defined as the luminance of a surface that emits or reflects light at a level that produces a brightness of one candela per square meter (cd/m²). The bril is particularly relevant in contexts involving visual ergonomics and lighting design, where accurate measurements of perceived brightness are essential for optimizing visibility and comfort. The unit helps in correlating the intensity of light with human perception, facilitating discussions on lighting standards and recommendations across various applications.
Current Use
Today, the bril is used across various industries, including architecture, automotive, and lighting design, to quantify and communicate luminance levels effectively. It plays a crucial role in ensuring that lighting solutions meet both functional and aesthetic requirements. In architectural design, luminance levels are essential for creating comfortable environments that enhance productivity and well-being. The automotive industry utilizes the bril to assess dashboard brightness and headlight effectiveness, ensuring that drivers have optimal visibility at night. Additionally, the bril is applied in the field of display technologies, where it helps in calibrating screens and monitors for accurate color rendering and brightness consistency. Countries such as the United States and those within the European Union utilize the bril in their lighting regulations and standards to promote safe and effective lighting practices.
Fun Fact
The bril was created to simplify discussions about lighting design, making it more accessible to non-scientists.

Candela per Square Centimeter
luminance • Non-SI
Definition
The candela square centimeter (cd/cm²) is a derived unit of luminance, defined as the luminous intensity of one candela distributed over an area of one square centimeter. It quantifies how bright a surface appears when illuminated, taking into account the human eye's sensitivity to different wavelengths of light. This unit is particularly useful in assessing the brightness of small light sources or surfaces in optical applications, as it conveys a clear sense of how much light is being emitted per unit area. The candela itself is one of the seven base SI units, representing the intensity of light emitted in a particular direction, making the cd/cm² a critical measure in fields such as photometry and lighting design.
History & Origin
The concept of luminance and related units like the candela square centimeter arose from the need to quantify light's effect on the human visual system. The International System of Units (SI) established the candela in 1979 as a base unit for luminous intensity, which subsequently led to the creation of derived units such as the cd/cm² to measure luminance. This evolution was part of a broader effort to standardize measurements in physics and engineering, ensuring consistent and accurate communication of light-related data across various fields. The adoption of the cd/cm² specifically allows for the assessment of small light sources and their impact on visibility, crucial for applications in photography, display technologies, and visual ergonomics.
Etymology: The word 'candela' is derived from the Latin term for 'candle', signifying a source of light, while 'centimeter' combines the Latin 'centi-' meaning 'one hundred' with the Greek 'metron' meaning 'measure', thus referring to a measure of one hundredth of a meter.
