SwitchExplanation
This page converts Apostilbs into Millicandela per Square Meter using fixed luminance constants anchored to candela per square meter. The direct answer, calculator, and common values table all follow the same factor.
Formula: Millicandela per Square Meter = Apostilbs × 318.309886. 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.
Apostilbs (asb): a legacy luminance unit tied to a fixed candela-per-square-meter equivalent.
Millicandela per Square Meter (mcd/m2): a very small luminance unit equal to one thousandth of a cd/m².
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.
