Stilbs to Nits

Snapshot

1 Stilbs equals 10,000 Nits. Conversion Encyclopedia uses the same fixed conversion basis across the calculator, common values, and reverse page for this page.

Reference basis: This conversion uses fixed luminance constants anchored to candela per square meter.
Example: For 5 Stilbs, the result equals 50,000 Nits.
Use the reverse page if you need the opposite direction with the same basis.

Explanation

This page converts Stilbs into Nits using fixed luminance constants anchored to candela per square meter. The direct answer, calculator, and common values table all follow the same factor.

Formula: Nits = Stilbs × 10,000. Why: legacy luminance units such as foot-lamberts, lamberts, apostilbs, and stilbs each use fixed cd/m² equivalents, so the calculator normalizes through candela per square meter before applying the target unit.

Stilbs (sb): a large legacy luminance unit equal to a fixed multiple of candela per square meter.

Nits (nit): a common display-brightness term numerically equal to candela per square meter.

This route is useful when comparing modern display-brightness values with legacy luminance units used in projection, cinema, and older photometric references.

Because the route stays inside one cd/m2-based luminance model, the mirror page reverses the same constants without changing the underlying assumptions.

Method & Luminance Basis

Method basis: both units reduce through candela per square meter, then apply the fixed target-unit luminance relationship.
Applied factor: 1 Stilbs = 10,000 Nits.
Consistency rule: calculator output and table values use the same constants and rounding policy.
