Luminous Intensity Converter
Comprehensive Luminous Intensity Converter
Luminous intensity quantifies the perceived power emitted by a light source in a particular direction. Expressed in candles (international), this parameter is essential in lighting design, optical engineering, and various scientific applications. Our Luminous Intensity Converter allows you to convert between different definitions of a candle—including German, UK, pentane, Hefner, and more—ensuring precise and consistent results across different standards.
What Units Are Covered?
Our converter supports a complete list of luminous intensity units with conversion factors defined relative to candle (international) [c]:

How Does It Work?
Our converter uses a two-step process:
Convert to the Base Unit:
The input value is first converted to candle (international) using the conversion factor of the selected “From” unit.Convert to the Target Unit:
The value in candle (international) is then converted to your chosen “To” unit using its corresponding conversion factor.
This method ensures accurate and consistent conversions across various luminous intensity standards.
