ABV Calculator

ABV Calculator computes alcohol by volume from two gravity measurements: Original Gravity (OG) and Final Gravity (FG). It targets homebrewers, craft beverage producers, and QA analysts who need quick, reproducible ABV values during fermentation planning and post-fermentation evaluation.
Conceptually, ABV is derived from the gravity difference using a standard conversion constant. The tool accepts SG inputs, validates ranges, and applies optional temperature compensation to improve accuracy when readings deviate from standard conditions.
Key differentiators include a straightforward workflow (two inputs, a clear result), robust input validation, and the ability to export a batch summary in future updates. It supports common brewing scenarios, wine-making checks, and beverage QC where ABV matters.
Core features include defined input validation, precise formatting of ABV to one decimal place, and consistent handling of edge cases such as FG>OG or missing data.
