Explanation

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

Formula: Stilbs = Candela per Square Meter × 0.0001. 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.

Candela per Square Meter (cd/m2): the SI luminance unit used for displays, imaging, and photometric measurement.

Stilbs (sb): a large legacy luminance unit equal to a fixed multiple of 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 Candela per Square Meter = 0.0001 Stilbs.
Consistency rule: calculator output and table values use the same constants and rounding policy.
