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 Photometric Measurement Tool is designed to convert illuminance values between different units, primarily focusing on the measurement of light intensity as perceived by the human eye. This tool uses the unit of lumens per square meter (lux) and other related units to provide accurate readings for various applications, including architectural lighting, photography, and environmental studies.
Photometric measurements are standardized by international organizations such as the International Organization for Standardization (ISO) and the International Commission on Illumination (CIE). These standards ensure consistency and reliability in measuring light, allowing professionals to make informed decisions based on accurate data.
The study of photometry dates back to the 19th century when scientists began to explore the properties of light. Over the years, advancements in technology have led to the development of sophisticated instruments and methodologies for measuring light. Today, photometric measurements are integral in fields such as engineering, design, and environmental science.
To illustrate the use of the Photometric Measurement Tool, consider a scenario where you need to convert 500 lux to foot-candles. Using the conversion factor (1 lux = 0.092903 foot-candles), the calculation would be:
[ 500 , \text{lux} \times 0.092903 = 46.4515 , \text{foot-candles} ]
This example highlights the tool's capability to facilitate quick and accurate conversions.
Photometric units are essential for various applications, including:
