SwitchExplanation
This page converts Lamberts 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 = Lamberts × 0.31831. 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.
Lamberts (L): a legacy luminance unit with a fixed candela-per-square-meter equivalent.
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.
