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'.
Lumen per Square Meter Steradianlm/m²·sr
Target UnitThe lumen per square meter steradian (lm/m²·sr) quantifies the luminous intensity emitted per unit area in a specific direction within a solid angle. It is derived from the lumen, which measures the total quantity of visible light emitted by a source, and the steradian, the unit of solid angle in three-dimensional space. This unit is pivotal in characterizing how light is distributed across surfaces and is essential for understanding the effectiveness of lighting in various applications.
Current Use
Lumen per square meter steradian is widely used in the fields of lighting design, architecture, and photography to quantify and evaluate the effectiveness of lighting systems. It helps in determining how evenly light is distributed within a space and is critical in optimizing illumination for energy efficiency and comfort. This unit is also utilized in scientific research and industrial applications where precise lighting conditions are necessary.
Fun Fact
The lumen is defined based on the sensitivity of the human eye, making it a subjective measurement.

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.

luminance • Non-SI
Definition
The lumen per square meter steradian (lm/m²·sr) quantifies the luminous intensity emitted per unit area in a specific direction within a solid angle. It is derived from the lumen, which measures the total quantity of visible light emitted by a source, and the steradian, the unit of solid angle in three-dimensional space. This unit is pivotal in characterizing how light is distributed across surfaces and is essential for understanding the effectiveness of lighting in various applications.
History & Origin
The lumen as a unit of luminous flux was established in the late 19th century, while the steradian was defined in 1888. The combination of these two units into the lumen per square meter steradian emerged as the need for precise measurement of lighting conditions in architectural and engineering applications grew in the mid-20th century.
Etymology: The term 'lumen' is derived from the Latin word for 'light', while 'steradian' combines 'stereos' (solid) and 'adian' (angle), indicating a measure of solid angle in three dimensions.
Current Use
