The candela per square meter (cd/m²), commonly referred to as "nits," is a unit of measurement for luminance. It quantifies the amount of light emitted from a surface in a specific direction, per unit area. This measurement is crucial for assessing the brightness of displays, lighting fixtures, and other surfaces that emit light.
The candela per square meter is standardized by the International System of Units (SI) and is derived from the base unit of luminous intensity, the candela (cd). One candela per square meter is equivalent to one candela of luminous intensity emitted from a surface area of one square meter. This standardization ensures consistency in measuring brightness across various applications.
The concept of luminance has evolved significantly since the early days of photometry. The candela was defined in the late 19th century, and the term "candela per square meter" was introduced as a way to quantify brightness in a more practical manner. Over the years, advancements in technology have led to the widespread use of this measurement in various fields, including television, computer displays, and architectural lighting.
To illustrate the use of the candela per square meter, consider a light source that emits 1000 candelas uniformly across a surface area of 2 square meters. The luminance can be calculated as follows:
[ \text{Luminance (cd/m²)} = \frac{\text{Luminous Intensity (cd)}}{\text{Area (m²)}} ]
[ \text{Luminance} = \frac{1000 , \text{cd}}{2 , \text{m²}} = 500 , \text{cd/m²} ]
This calculation shows that the surface has a luminance of 500 cd/m².
The candela per square meter is widely used in various industries, including:

The lumen (symbol: lm) is the SI unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time. It quantifies the perceived power of light as it relates to human vision, making it an essential measurement in fields such as photography, lighting design, and architecture.
The lumen is standardized under the International System of Units (SI) and is defined based on the luminous efficacy of radiant energy. One lumen is equivalent to the light emitted by a uniform source of one candela over a solid angle of one steradian. This standardization ensures consistency in lighting measurements across various applications.
The concept of the lumen has evolved over time, with its origins tracing back to the early studies of light and vision. The term "lumen" was first introduced in the late 19th century as scientists sought to quantify light output in a way that was relatable to human perception. Over the decades, advancements in technology and a deeper understanding of photometry have led to the refinement of the lumen as a standard unit of measurement.
To illustrate the use of the lumen, consider a light bulb that emits 800 lumens. If you want to determine how many lumens are required for a room of 100 square feet to achieve a recommended illuminance level of 50 lux, you would calculate it as follows:
The lumen is widely used in various applications, including:
