You can use these calculators to calculate Alcohol By Volume (ABV), Original Gravity (OG), and Final Gravity (FG).

**Alcohol By Volume ABV Calculator | Brewer's Friend
**

Finds ABV based on gravity change.

**Alcohol by Volume Calculator
**

To establish the value of the alcohol content of a liquid when expressed in different ways.

**

Calculate original gravity, expected final gravity and expected alcohol by volume.

**Batch Statistics for Extract Base Recipes | Brewer's Friend
**

Find out your original gravity, expected final gravity and expected alcohol by volume.

**Equivalent Unit Drinks Calculator
**

This gives the direct relationship between *drink units* in any two of 16 different countries.

**Hydrometer Temperature Adjustment Calculator | Brewer's Friend
**

Calculates actual specific gravity, correcting for the sample wort temperature and the hydrometer's calibration.

**Units of Alcohol Calculator
**

This allows the number of units of alcohol in a given quantity of liquid to be found, given that the percentage of alcohol by volume (AbV) is known.
It applies ONLY to the UK.

**Units of Drink Calculator
**

This allows the number of units of alcohol in a given quantity of liquid to be found, given that the percentage of alcohol by volume (AbV) is known. Adjustable, so as to cover the *standards* of 16 different countries.
