API, OpenAPI and WebMCP documentation

Explanation

The converter converts uk proof into abv per mille by normalizing both strength scales through ABV percent. Formula: permille = proof (UK) × 5.715. Both directions stay aligned because the calculator, common values, and mirror page all use the same ABV-based relationship. 100 UK proof equals 57.15% ABV. Per mille here means parts per thousand of ABV by volume.

This is the practical way to compare labeling systems such as ABV, US proof, UK proof, and related fractional strength formats without mixing incompatible proof definitions.

Method & Strength Basis

Method basis: fixed alcohol-strength definitions normalized through ABV percent, including the exact US and UK proof relationships used on this page.
Applied factor: 1 UK Proof = 5.715 ABV Per Mille.
Consistency rule: calculator output and common-value rows use the same ABV-based strength constants in both directions.
