Use this tool to easily convert luminance values to illuminance measurements.
How to Use the Luminance to Illuminance Calculator
This calculator helps you convert luminance (cd/m²) to illuminance (lux). Simply input the luminance in candelas per square meter (cd/m²) and the distance in meters (m) from the light source to the point of measurement, then click the “Calculate” button to get the illuminance in lux.
Steps to Use:
- Enter the luminance value in cd/m².
- Enter the distance from the light source in meters.
- Click the “Calculate” button.
- The result will be displayed in the “Result” field as illuminance in lux.
How It Calculates the Results:
The formula used for the calculation is:
Illuminance (lux) = Luminance (cd/m²) / (Distance (m)²)
This formula considers that illuminance is inversely proportional to the square of the distance from the light source.
Limitations:
This calculator assumes a point light source and does not account for factors like light scattering, reflection, or absorption. It works best for scenarios where these factors are negligible.
