SwitchExplanation
This page converts Foot-Lamberts 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 = Foot-Lamberts × 3.426259. 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.
Foot-Lamberts (fL): a legacy luminance unit often used in projection and cinema display contexts.
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.
