Nits to Lamberts

Snapshot

1 Nits equals 0.000314 Lamberts. 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 Nits, the result equals 0.001571 Lamberts.
Use the reverse page if you need the opposite direction with the same basis.

Explanation

This page converts Nits 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 = Nits × 0.000314. 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.

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

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 & Luminance Basis

Method basis: both units reduce through candela per square meter, then apply the fixed target-unit luminance relationship.
Applied factor: 1 Nits = 0.000314 Lamberts.
Consistency rule: calculator output and table values use the same constants and rounding policy.
