SwitchExplanation
Formula: UK Proof = ABV Fraction × 174.978128. 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 Fraction (fraction): a 0-to-1 alcohol-strength representation where 1 equals 100% ABV.
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.

Frequently Asked Questions
Why does this route go through ABV percent?
ABV percent is the common reference layer for this family, so proof, fraction, and per-mille strength values stay consistent and reversible.
How do I reverse ABV Fraction to UK Proof?
Use the switch button or open the UK Proof to ABV Fraction page to apply the same alcohol-strength relationship in reverse.
Can I use decimal inputs?
Yes. Decimal strength values are supported for beverage labeling, spirits references, lab work, and batching calculations.
