## What is BrewingCalc?

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.

### 2/5 — IBU Calculator totally wrong!

*2026-08-04*

I made IBU calculations with two Apps, and the results are completely different, since I already had the real results, this App has issues!

### 5/5 — Класс!

*2020-04-08*

Пользуюсь калькулятором рефрактометра, очень удобно, что он под рукой, не надо идти к компьютеру.

### 5/5 — Только положительные эмоции

*2019-10-01*

Очень удобная программа, знакомый пивовар облизывается так как на андроиде такой нет.

### 1/5 — Inaccurate

*2019-08-11*

Not much point to an app that calculates the ABV and comes up with a value that is different to that calculated by every other source I could find.

### 5/5 — Great little app

*2018-07-15*

I got this just to do refractometer corrections but it also does a bunch more. 
Thanks for putting the time in to develop this.

### 5/5 — Супер

*2018-04-06*

Отличная программа!!!! Все необходимые калькуляторы для пивовара. Огромное спасибо!!

### 3/5 — Not updated. Has a bug

*2018-03-27*

Good layout. Useful formulas for converting between Brix/Plato and SG and calculating alcohol content, but it has a bug and the output value does not change for ABV table content when the input values are changed. It's hasn't been updated since 2014.

### 5/5 — Pivovar

*2016-12-16*

Спасибо ,отличная прога!🍺

### 5/5 — Спасибо

*2015-10-16*

Отличное приложение!

### 5/5 — Класс

*2015-02-14*

Отличное приложение, удобство в том что всегда под рукой... Не нужен компьютер. Быстро и без всяких проблем считает горечь, также порадовала функция расчета показаний рефрактометра, ну, и расчет крепости тоже
