API, OpenAPI and WebMCP documentation

Explanation

The converter converts foot-lamberts into millicandela per square meter by normalizing both luminance units through candela per square meter. Formula: mcd/m2 = fL × 3426.2590996. That keeps the snapshot, calculator, common values, and mirror page aligned on one luminance basis.

This is useful for display brightness checks, projection calibration, and imaging workflows where legacy photometric units and modern cd/m²-based measurements need to match cleanly.

Method & Luminance Basis

Method basis: both units reduce through candela per square meter, then apply the fixed target-unit luminance relationship.
Applied factor: 1 Foot-Lamberts = 3,426.2591 Millicandela per Square Meter.
Consistency rule: calculator output and table values use the same constants and rounding policy.
