Photometry & Imaging Converters
Convert luminance units for displays, projection, and imaging calibration using fixed cd/m2-based constants.
Scope & Verification
This hub groups related converter families so you can move from the category level to exact routes with one clear basis per page.
- Families are split so exact-factor, profile-based, density-based, and estimate-style pages do not collapse into one generic answer.
- Leaf pages keep calculator, common values, FAQ, and reverse routes aligned to the same assumption.
- Methodology and verification pages document how those assumptions are chosen and checked.

Machine access
Conversions in this hub are represented by the canonical photometry-imaging family and its registered source and target units.
Its 56 published directions use the same canonical engine through the website, JSON API, OpenAPI and WebMCP.
API & Agent documentationExplanation
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.
The Photometry Imaging hub maps related converter families into directional routes with consistent assumptions.
Open a family hub to reach leaf pages with direct answers, calculator output, and reverse links built on the same constants.
Questions & answers
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.
