Unit Explanations
Candle (International)cd
Source UnitThe candle (symbol: cd) is a unit of luminous intensity in the International System of Units (SI), defined based on the electromagnetic spectrum. Specifically, it represents the amount of light emitted by a source in a particular direction. The modern definition is based on a specific light source, namely, a blackbody radiator at a temperature of 2042 K. This unit allows for the quantification of light output in a manner that is consistent and reproducible, making it crucial for various scientific and industrial applications. It is essential in providing a standard for measuring light intensity, which can vary significantly depending on the source and environmental conditions.
Current Use
Today, the candle is primarily used in fields related to photometry and lighting design, where accurate measurement of luminous intensity and brightness is essential. In the entertainment industry, for instance, it assists in designing stage lighting and visual effects, ensuring that lighting professionals can achieve the desired atmospheric effects. The candle is also crucial in scientific research, particularly in studies involving optical properties and the behavior of light in different materials. Countries worldwide, including the United States and members of the European Union, utilize the candle for standardization in lighting products, ensuring compliance with safety and performance standards. Furthermore, it plays a vital role in the manufacturing of lighting fixtures, where precision in light output is necessary for energy efficiency and consumer satisfaction.
Fun Fact
The candle was first standardized in 1909 by an international agreement.
Candle (German)cd
Target UnitThe German candle, known as 'Kerze', is a historical unit of luminous intensity that was defined as the light emitted by a standard candle made from a specific composition of tallow. It is equivalent to one candela in the International System of Units (SI). The candle was originally defined based on the luminous intensity of a candle burning a specified material, which was tallow until the late 19th century. The unit was used primarily in Germany and other German-speaking regions and was an important standard in the measurement of light before the widespread adoption of the candela. Today, the candle as a unit has largely been replaced by the candela, which provides a more consistent measurement based on the physical properties of light.
Current Use
The German candle is rarely used today, as it has been largely replaced by the SI unit, the candela. However, its historical context is significant in lighting design and historical studies of measurement. In some niche applications, particularly in historical recreations or studies, the German candle may be referenced to provide context or continuity in discussions of light measurement. While the modern lighting industry relies on standardized measurements, the legacy of the German candle still influences how we understand luminous intensity. In education, particularly in physics and engineering courses, the German candle may be mentioned when discussing the evolution of measurement units in photometry. This historical context provides a foundation for understanding modern practices in lighting and photometric standards.
Fun Fact
The candle was used as a standard unit of light long before the advent of electric lighting.

Definition
The candle (symbol: cd) is a unit of luminous intensity in the International System of Units (SI), defined based on the electromagnetic spectrum. Specifically, it represents the amount of light emitted by a source in a particular direction. The modern definition is based on a specific light source, namely, a blackbody radiator at a temperature of 2042 K. This unit allows for the quantification of light output in a manner that is consistent and reproducible, making it crucial for various scientific and industrial applications. It is essential in providing a standard for measuring light intensity, which can vary significantly depending on the source and environmental conditions.
History & Origin
The origin of the candle as a unit of measurement dates back to the early use of candles in various cultures. Originally, candles were made from tallow or beeswax and served as a primary source of light in homes and public spaces. The need for a standard measure of light output became evident as technology advanced and the use of electric lighting became widespread. In the late 19th century, various attempts were made to standardize luminosity, but it wasn't until 1909 that the 'international candle' was formally defined. This definition was crucial, as it marked a transition from a historical artifact to a scientifically grounded unit of measurement.
Etymology: The word 'candle' derives from the Latin 'candela', which means 'to shine'. This etymology reflects the candle's role as a source of light, capturing its essence in illumination.
