Explanation

Formula: UK Proof = ABV Per Mille × 0.174978. Why: proof scales are normalized through ABV percent using fixed legal definitions, including US proof = 2 times ABV and 100 UK proof = 57.15% ABV.

ABV Per Mille (permille): an alcohol-strength scale expressed in parts per thousand by volume.

UK Proof (proof (UK)): a historical proof scale where 100 proof equals 57.15% ABV.

This route is useful when translating between ABV and proof systems for beverage labeling, spirits references, and dilution planning.

This conversion is purely multiplicative because both strength scales reduce through ABV percent using fixed proof and fractional definitions with no offset.

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 ABV Per Mille = 0.174978 UK Proof.
Consistency rule: calculator output and common-value rows use the same ABV-based strength constants in both directions.
