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.
MillilambertmL
Target UnitThe millilambert (mL) is a unit of luminance, a measure of the brightness of a surface that emits or reflects light. Specifically, one millilambert is defined as one-thousandth of a lambert, which itself is based on the luminance produced by a surface emitting light uniformly at a rate of one lumen per square centimeter. This unit is particularly useful in fields such as photography, television, and lighting design, where precise measurements of brightness are essential for achieving desired visual effects. It is important to note that the millilambert is not an SI unit, but it is still widely used in various industries for its practicality in expressing small values of luminance. The relationship between the lambert and the millilambert allows for convenient calculations when working with varying levels of brightness.
Current Use
The millilambert is predominantly used in industries that require precise control over brightness levels, such as film and television production, photography, and architectural lighting design. In these fields, accurate luminance measurements are critical for achieving desired visual outcomes. For instance, in film and television, cinematographers often use the millilambert to calibrate lighting setups, ensuring consistency across scenes. Additionally, in architectural lighting, designers utilize this unit to create aesthetically pleasing environments by measuring the luminance of various surfaces. Countries like the United States and Germany, where film and media industries thrive, frequently use the millilambert for such applications. Moreover, as digital displays become more prevalent, the millilambert is increasingly relevant in the calibration of screens to ensure optimal brightness and contrast levels, emphasizing its importance in contemporary technology.
Fun Fact
The lambert was named after Johann Heinrich Lambert, who made significant contributions to the field of optics.

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.

Millilambert
luminance • Non-SI
Definition
The millilambert (mL) is a unit of luminance, a measure of the brightness of a surface that emits or reflects light. Specifically, one millilambert is defined as one-thousandth of a lambert, which itself is based on the luminance produced by a surface emitting light uniformly at a rate of one lumen per square centimeter. This unit is particularly useful in fields such as photography, television, and lighting design, where precise measurements of brightness are essential for achieving desired visual effects. It is important to note that the millilambert is not an SI unit, but it is still widely used in various industries for its practicality in expressing small values of luminance. The relationship between the lambert and the millilambert allows for convenient calculations when working with varying levels of brightness.
History & Origin
The millilambert was introduced in the context of the need for precise measurement of luminance in visual media. The concept of luminance emerged as scientists began to explore the properties of light and its interaction with surfaces in the early 20th century. The lambert, the base unit for luminance, was named after the German mathematician and physicist Johann Heinrich Lambert, who made significant contributions to the understanding of light and color. This need for fine measurements led to the creation of the millilambert, providing a more granular scale for luminance measurement, particularly in practical applications.
Etymology: The term 'millilambert' combines the prefix 'milli-', meaning one-thousandth, with 'lambert', named after Johann Heinrich Lambert.
