Explanation

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

Formula: Lamberts = Foot-Lamberts × 0.001076. 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.

Lamberts (L): a legacy luminance unit with a fixed candela-per-square-meter equivalent.

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 & Reference

Method basis: exact conversion formula shown in Direct Answer.
Applied factor: 1 Foot-Lamberts = 0.001076 Lamberts.
Consistency rule: calculator output and table values use the same constants and rounding policy.
