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.

This unit is especially important in defining how bright a surface appears under specific lighting conditions and is crucial for ensuring appropriate illumination in various environments, from art galleries to roadways.
History & Origin
The term 'candela' is derived from the Latin word 'candela,' meaning 'candle,' which was historically used to describe the light produced by a candle. The concept of measuring light intensity has evolved significantly over time, with early definitions rooted in the natural candle standard. The modern definition of the candela was established in 1948 during the International Conference on Weights and Measures (CGPM) in response to the need for a consistent and reproducible standard for light measurement. The kilocandela, as a multiple, was adopted to provide a more manageable scale for luminance measurements without losing precision.
Etymology: The word 'kilocandela' combines the prefix 'kilo-' meaning 'thousand' with 'candela,' which refers to the base unit of luminous intensity.
