What is the luminance converter?
The luminance converter is a collection of calculators for changing one luminance unit into another. Convert luminance units for displays, lighting, photometry, optical instruments, and visual performance calculations.
Luminance conversions are used for screens, lighting, photometry, optical instruments, visibility studies, and display specifications.
Available luminance units
This category includes the following units:
- Candela per Square Meter (cd/m2)
- Nit (nt)
- Stilb (sb)
- Lambert (L)
- Foot-lambert (fL)
Common luminance use cases
Use this category when the same measurement appears in different unit systems, data sheets, calculators, reports, or regional conventions.
- Luminance conversions help compare measurements across specifications, calculators, labels, and technical references.
- Use this category when source data and target documents use different luminance units.
- The dedicated conversion pages show formulas, examples, tables, related pages, and FAQ for individual unit pairs.

Most wrong answers come from mixing unit systems, rounding too early, or choosing a unit that looks similar but means something different.
- Do not hide the original luminance unit when copying a result into a report, label, or calculator.
- Do not round intermediate values when the result will be reused in another formula.
- Check whether the source and target units describe the same physical quantity before comparing luminance values.
