How to Convert Candelas to Hefnerkerze
To convert candelas to hefnerkerze, multiply the luminous intensity by the following conversion ratio: 1.1074197 hefnerkerze/candela.
Since one candela is equal to 1.1074197 hefnerkerze, you can use this simple formula to convert:
The luminous intensity in hefnerkerze is equal to the luminous intensity in candelas multiplied by 1.1074197.
For example, here's how to convert 5 candelas to hefnerkerze using the formula above.
How Many Hefnerkerze Are in a Candela?
There are 1.1074197 hefnerkerze in a candela, which is why we use this value in the formula above.
Our candela to hefnerkerze calculator automatically converts your luminous intensity measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Candelas and hefnerkerze are both units used to measure luminous intensity. Keep reading to learn more about each unit.
What Is a Candela?
Fundamental SI base unit of luminous intensity. It serves as a primary reference unit for measuring luminous intensity across scientific and practical applications. [1]
The candela is classified as an International System of Units (SI) unit of luminous intensity. Candelas can be abbreviated as cd; for example, 1 candela can be written as 1 cd.
As the primary coherent reference unit for luminous intensity in this category, all other luminous intensity units are mathematically anchored to the candela (cd).
In practice, candelas (cd) are widely used across standard luminous intensity applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
What Is a Hefnerkerze?
A hefnerkerze is a unit of luminous intensity equal to 0.903 candelas (cd), the base unit for luminous intensity. Historical German photometric candle standard (≈ 0.903 cd). [2]
The hefnerkerze is classified as a standard unit of luminous intensity. Hefnerkerze can be abbreviated as HK; for example, 1 hefnerkerze can be written as 1 HK.
When working with hefnerkerze (HK) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, hefnerkerze (HK) are widely used across standard luminous intensity applications within international standard workflows, engineering documentation, and technical data sheets.
When converting luminous intensity between candelas (cd) and hefnerkerze (HK), keep full floating-point precision (1 cd = 1.1074197 HK; 1 HK = 0.903 cd) during intermediate calculations and round only the final hefnerkerze figure to match your instrument tolerance.
