Unit Explanations
Candela per Square Metercd/m²
Source UnitThe candela per square meter (cd/m²), commonly referred to as 'nits', is a derived unit of luminance in the International System of Units (SI). It quantifies the luminous intensity emitted by a surface in a given direction per unit area. Specifically, it defines how much light is emitted from a surface that has a luminous intensity of one candela and covers an area of one square meter. This unit is crucial in fields such as photography, display technology, and lighting design, as it allows for the assessment of brightness and visual comfort. The concept of luminance is fundamental in understanding how light interacts with surfaces and affects human perception. It plays a vital role in optimizing lighting conditions and evaluating the performance of displays and lighting fixtures in various environments.
Current Use
The candela per square meter is widely used across various industries, including electronics, automotive, architecture, and photography. In the electronics industry, it is crucial for evaluating display brightness in televisions, computer monitors, and smartphones, influencing consumer choices and design standards. In the automotive sector, luminance standards ensure that dashboard displays and exterior lights meet safety regulations. Architectural lighting design relies on cd/m² to create visually appealing environments while ensuring adequate illumination levels. In photography, achieving the correct luminance is essential for proper exposure and image quality. Countries such as the United States, Germany, and Japan have adopted this unit in their standards for light measurement, contributing to a global understanding of luminance.
Fun Fact
The term 'nit' is derived from the Latin word 'nitere', meaning 'to shine'.
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.

The concept of luminance is fundamental in understanding how light interacts with surfaces and affects human perception. It plays a vital role in optimizing lighting conditions and evaluating the performance of displays and lighting fixtures in various environments.
History & Origin
The candela per square meter originated from the need to measure light's visual impact on surfaces. In the early 20th century, the understanding of light properties and their effects on human vision was still developing. The International Commission on Illumination (CIE) conducted extensive research to define standards for various light measurements. The candela, established as the SI base unit of luminous intensity in 1979, became integral to this system. The derivation of luminance from the candela marked a significant step in quantifying light's interaction with surfaces, thereby enhancing the precision of lighting design and evaluation.
Etymology: The term 'candela' is derived from the Latin word for 'candle', reflecting the historical use of candles as a standard light source.

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.
