Luminance To Illuminance Calculator – Accurate Measurements

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:

  1. Enter the luminance value in cd/m².
  2. Enter the distance from the light source in meters.
  3. Click the “Calculate” button.
  4. 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.
