Verifying your Luminance Converter result is correct

A result that looks plausible can still be wrong. These are the checks that actually prove it, including a round-trip and a known-answer comparison.

How to use

  1. Run the tool a second time in the opposite direction and confirm you get the original input back.
  2. Compare against a known-answer value for a simple input you can compute independently.
  3. Check the length, encoding and character set of the output — silent truncation is the most common failure.
  4. If the result feeds another system, validate it there too; a locally correct value can still be rejected downstream.
