Description
BrewingCalc is a professional toolkit for homebrewers — clean, fast, and built for serious brewing.
Whether you're calculating bitterness, estimating ABV, or converting between metric and US units, BrewingCalc gives you all the tools you need in one place.
CALCULATORS INCLUDED
IBU (Glenn Tinseth) — Calculate International Bitterness Units for up to 5 hop additions. Enter hop weight, alpha acid %, boil time, batch volume, and wort gravity. Get per-hop and total IBU.
ABV Table — Determine alcohol by volume using a precision 60-point specific gravity interpolation table. Supports both Plato and SG inputs.
ABV Formula — Temperature-corrected ABV calculation using a polynomial formula. Accounts for measurement temperature of both original and final gravity readings.
Calories — Estimate total and per-100ml calories from original gravity, final gravity, and batch volume. Uses the Real Extract (RE) method.
Brix / Refractometer — Convert refractometer readings to gravity and ABV. Two modes: enter original and final Brix, or work backwards from current gravity and corrected Brix. Includes wort correction factor support.
Unit Converters — Four precision converters:
Volume: litres, millilitres, decalitres, US/UK gallons, fl oz, pints
Weight: kilograms, grams, pounds, ounces
Temperature: Celsius, Fahrenheit, Kelvin
Gravity: Plato ↔ Specific Gravity
DESIGNED FOR BREWERS
All formulas follow established brewing science — Glenn Tinseth's IBU model, the Real Extract calorie method, and standard Brix correction. No ads, no subscriptions, no account required.
Works great on both iPhone and iPad.
