SwitchExplanation
Formula: ABV Per Mille = UK Proof × 5.715. 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.
UK Proof (proof (UK)): a historical proof scale where 100 proof equals 57.15% ABV.
ABV Per Mille (permille): an alcohol-strength scale expressed in parts per thousand by volume.
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.
