Candle (International)
c
Definition
The Candle (International) is the SI base unit of luminous intensity, defined as the luminous intensity in a given direction of a source that emits monochromatic radiation of frequency 540×10¹² hertz and has a radiant intensity in that direction of 1/683 watt per steradian.
History/Origin
The international candle was established in 1948 as part of the International System of Units (SI). It replaced earlier candle standards and provides a precise, reproducible definition based on fundamental physical constants, ensuring consistency in light measurement worldwide.
Current Use
Widely used as the standard unit for measuring luminous intensity in scientific research, lighting design, and photometric applications. It is essential for calibrating light sources, designing lighting systems, and ensuring accurate light measurements in various industries.

Lumen per Steradian
lm/sr
Definition
The Lumen per Steradian is a unit of luminous intensity that is dimensionally equivalent to the candela. It represents the luminous flux emitted in a given direction per unit solid angle, providing an alternative way to express luminous intensity in terms of luminous flux.
History/Origin
Derived from the fundamental definition of the candela, which is one lumen per steradian. It provides an alternative perspective on luminous intensity by emphasizing the relationship between luminous flux and solid angle in photometric measurements.
Current Use
Widely used in theoretical photometry and in calculations where the luminous flux aspect of light is emphasized. It provides a direct link to the fundamental definitions of light measurement and is interchangeable with the candela in most practical applications.
