API, OpenAPI and WebMCP documentation

Explanation

The converter converts abv fraction into abv percent by normalizing both strength scales through ABV percent. Formula: % ABV = fraction × 100. Both directions stay aligned because the calculator, common values, and mirror page all use the same ABV-based relationship. ABV fraction is a 0 to 1 scale where 1 equals 100% ABV.

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 ABV-percent normalization used to restate strength as percent, fraction, or per-mille with no offset.
Applied factor: 1 ABV Fraction = 100 ABV Percent.
Consistency rule: calculator output and common-value rows use the same ABV-based strength constants in both directions.

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.
