Unit Explanations
Candela per Square Metercd/mĀ²
Source UnitThe candela per square meter (cd/mĀ²), 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/mĀ² 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'.
Stilbsb
Target UnitThe stilb (symbol: sb) is a unit of measurement for luminance, which quantifies the amount of light emitted or reflected from a surface per unit area. Specifically, it represents the luminous intensity in candelas per square meter (cd/mĀ²), where one stilb corresponds to one candela per square meter. The stilb is particularly useful in fields such as optical engineering, photography, and vision science, allowing for precise quantification of light levels in various contexts. It helps in the assessment of visibility, brightness, and the effectiveness of lighting systems, informing design and safety standards in environments ranging from workplaces to public spaces.
Current Use
Today, the stilb is primarily used in specialized fields such as photometry, lighting design, and visual ergonomics. It plays a significant role in industries like film and television, where precise luminance measurements are critical for achieving the desired visual effects and maintaining consistency across lighting setups. In architectural design, the stilb aids in ensuring that spaces are adequately illuminated for comfort and safety. Countries with advanced lighting technology, such as Germany, the United States, and Japan, frequently employ the stilb in research and development to optimize lighting solutions for various applications, including public spaces, work environments, and outdoor areas. Furthermore, the stilb is referenced in regulatory standards for workplace illumination, ensuring compliance with safety and efficiency guidelines.
Fun Fact
The stilb is not as commonly used as other units like the lux, but it provides a more direct measure of luminance.

luminance ā¢ Non-SI
Definition
The candela per square meter (cd/mĀ²), 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.

History & Origin
The stilb was introduced in the mid-20th century as a part of the efforts to standardize measurements of light and visibility. The need for a clear and consistent unit arose as industries, particularly those related to photography and theatrical lighting, required reliable metrics to evaluate brightness and luminance. The term 'stilb' is derived from the Greek word 'stilbos,' which means 'shining' or 'gleaming,' reflecting the unit's focus on light. This unit emerged during a period when many contemporary measurement systems were being developed or refined, leading to a more unified approach in scientific and engineering fields.
