Photometry & Imaging Converters

Convert luminance units for displays, projection, and imaging calibration using fixed cd/m2-based constants.

Explanation

This hub focuses on luminance unit conversions used in imaging, display calibration, and projection workflows. Every factor is normalized through candela per square meter (cd/m2), enabling stable mirror conversions across SI and legacy photometric units.

How to use this hub

  1. Choose a converter family.
  2. If converting to/from grams from a volume unit, select an ingredient.
  3. For pure unit changes (volume↔volume or weight↔weight), use universal conversions.

If your conversion includes grams, you’ll choose an ingredient; otherwise you won’t.

Frequently Asked Questions

What quantity does this hub convert?

It converts luminance units, all normalized through candela per square meter (cd/m2).

Are these factors fixed?

Yes. They are fixed multiplicative factors with no offsets, so reverse pages remain consistent.

Can I use decimal values?

Yes. Decimal values are supported for practical display and projection tuning.
