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'.
Nitnt
Target UnitA nit is a unit of measurement for luminance, which quantifies the amount of light emitted from a surface in a given direction per unit area. Specifically, one nit is defined as one candela per square meter (cd/m²). This unit is essential in the fields of display technology, lighting, and vision science, where it is used to express the brightness of screens and other light-emitting surfaces. The human eye’s sensitivity to different wavelengths of light makes it crucial to measure luminance in nits, as it directly influences how we perceive images and colors on displays. The nit plays a vital role in ensuring that the brightness levels of screens are appropriate for different lighting conditions and user experiences.
Current Use
Nits are widely used in various industries to specify the brightness of displays, particularly in consumer electronics such as televisions, monitors, and smartphones. For example, high-end televisions may advertise brightness levels of 1000 nits or more, allowing for better visibility in bright rooms. In automotive applications, nits are crucial for dashboard displays and infotainment systems to ensure readability under varying light conditions. The gaming industry also utilizes nits to market monitors that deliver high dynamic range (HDR) content, where brightness levels significantly impact visual experiences. Additionally, nits are instrumental in compliance with safety regulations for outdoor advertising signage, where visibility is paramount. Countries across the globe, including the United States, Japan, and members of the European Union, utilize nits for product specifications and regulatory standards in display technologies, ensuring consistent performance and user satisfaction.
Fun Fact
The brightness level of 1 nit is approximately equivalent to the brightness of a candle viewed from a distance of 1 meter.

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.
