How to Convert Kilocandelas to Lumens per Steradian
To convert kilocandelas to lumens per steradian, multiply the luminous intensity by the following conversion ratio: 1,000 lumens per steradian/kilocandela.
Since one kilocandela is equal to 1,000 lumens per steradian, you can use this simple formula to convert:
The luminous intensity in lumens per steradian is equal to the luminous intensity in kilocandelas multiplied by 1,000.
For example, here's how to convert 5 kilocandelas to lumens per steradian using the formula above.
How Many Lumens per Steradian Are in a Kilocandela?
There are 1,000 lumens per steradian in a kilocandela, which is why we use this value in the formula above.
Our kilocandela to lumen per steradian calculator automatically converts your luminous intensity measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Kilocandelas and lumens per steradian are both units used to measure luminous intensity. Keep reading to learn more about each unit.
What Is a Kilocandela?
A kilocandela is a unit of luminous intensity equal to 1,000 candelas (cd), the base unit for luminous intensity. Searchlight & automotive headlamp intensity unit (1,000 cd). [1]
The kilocandela is classified as a metric and SI-compatible unit of luminous intensity. Kilocandelas can be abbreviated as kcd; for example, 1 kilocandela can be written as 1 kcd.
In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilocandela (kcd) a convenient decimal multiple of the candela (cd).
In practice, kilocandelas (kcd) are widely used across large-scale industrial, bulk, and macro-level luminous intensity specifications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Lumen per Steradian?
A lumen per steradian is a unit of luminous intensity equal to 1 candelas (cd), the base unit for luminous intensity. Exact SI definition of 1 candela (1 lm/sr = 1 cd). [2]
The lumen per steradian is classified as an International System of Units (SI) unit of luminous intensity. Lumens per Steradian can be abbreviated as lm/sr; for example, 1 lumen per steradian can be written as 1 lm/sr.
When working with lumens per steradian (lm/sr) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, lumens per steradian (lm/sr) are widely used across standard luminous intensity applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting luminous intensity between kilocandelas (kcd) and lumens per steradian (lm/sr), keep full floating-point precision (1 kcd = 1,000 lm/sr; 1 lm/sr = 0.001 kcd) during intermediate calculations and round only the final lumen per steradian figure to match your instrument tolerance.
