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'.
LambertL
Target UnitThe lambert (symbol: L) is a unit of luminance that quantifies the amount of visible light emitted or reflected from a surface in a particular direction. It defines the intensity of light per unit area, where one lambert is equal to one lumen per square centimeter. This measurement is particularly relevant in fields such as photometry and lighting design, as it helps in assessing how much light is perceived by the human eye from a given surface. The concept of luminance is essential for evaluating the brightness of surfaces in various lighting conditions and is crucial for ensuring adequate visibility in environments ranging from homes to workplaces.
Current Use
Today, the lambert is widely used in various industries, particularly in lighting and display technology. It is instrumental in the design and evaluation of lighting systems, helping engineers and designers ensure that spaces are adequately illuminated for their intended use. The lambert is also used in evaluating the luminance of screens in the television and computer industries, where accurate color rendering and brightness are critical for user experience. Although less common in everyday applications, it remains a vital unit in specialized fields such as cinematography, where consistent luminance levels are necessary for visual storytelling. Countries such as the United States and Germany, with strong foundations in photometric research, continue to utilize the lambert in both academic and industrial applications.
Fun Fact
The lambert is named after Johann Heinrich Lambert, who also contributed to our understanding of the inverse-square law of light.

Candela per Square Meter
luminance • Non-SI
Definition
The 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.
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.
