ABV (Alcohol By Volume) Calculator: If you are looking for a handy tool that does the calculation for you and tells the amount of alcohol in your beverage then you have come the right way. To help you understand the concept of ABV (Alcohol By Volume), we have detailed everything in step by step manner. 

You will find information on formulas for alcohol calculation and how to find the actual amount of alcohol present in any drink. This effortless and handy tool will make your calculations quicker and give you a thorough explanation of the concept.

What Does Percentage by Volume Mean in Alcohol?

It is a standard unit for determining how much alcohol (ethanol) is present in a given volume of alcoholic beverages. It is represented as a percentage of volume. This is the number of millilitres (mL) of pure ethanol present in 100 millilitres (mL) of a solution at 20 degrees Celsius (68 degrees Fahrenheit). It is also called ABV which is an abbreviation of ‘Alcohol by Volume’. It is used worldwide. Except in France & some neighbouring countries, a slightly different method is used.

Formulas of Alcohol by Volume Calculation

The usage of units of alcohol is a simple way to depict the alcohol level of a drink. Alcohol by volume is commonly used to denote these numbers. The ABV of a drink is expressed as a % of the total volume of the drink and indicates the amount of pure alcohol contained. These calculations use the specific gravity of an alcoholic liquid.

Here are the Formulae to Calculate the ABV: 

Alcohol by Volume Formula (Standard)

ABV = (OG - FG)×131.25

Alcohol by Weight (ABW) Formula

ABW = ABV × 0.79336

No. of Units of Alcohol = ABV × Volume / 1000

Here, OG = original gravity

FG = final gravity

Step by Step Guide on How to Calculate Alcohol by Volume in Mixed Drinks

  1. Check the OG & FG of a given alcoholic drink
  2. Use the formula to calculate the ABV of a drink.
  3. Check the type of your drink using the following table.
    • Beer: 2-6%
    • Cider: 4-8%
    • Wine: 8-20%
    • Tequila: 40%
    • Rum: 40% or greater
    • Brandy: 40% or greater
    • Gin: 40-47%
    • Whiskey: 40-50%
    • Vodka: 40-50%
  4. We can also calculate the units of alcohol using ABV.

Solved Example for Calculating the ABV of Your Drink

Example:

Calculate the ABV of a drink whose OG & FG is 1.1& 1.054 respectively. Also, calculate the total units of alcohol in 200 ml of a given drink.

Solution:

Here, OG = 1.1 & FG = 1.054

So, formula of ABV = (OG - FG) × 131.25 = 6.038 % 

By volume of a drink, we can say that it is a beer.

Now, we calculate units of Alcohol

No. of Units of Alcohol = ABV × Volume / 1000

= 6.038 × 200 /1000 = 1.2 units

So, in a given volume of beer, 1.2 units of alcohol is present.

FAQs on Alcohol by Volume ABV Calculator with Steps

1. What does 5% alcohol by volume actually mean?

5% alcohol by volume means that there is 0.6 oz of alcohol present in each serving.

2. What does 40% by volume alcohol mean?

40% by volume of alcohol means that the drink's liquid contains 40% alcohol in it.

3. How do you calculate the proof of alcohol by volume?

Proof of alcohol is equal to twice the measure of alcohol by volume in the US. A drink with 50% alcohol in it will be 100-proof.

4. Is ABV the same as alcohol percentage?

ABV percentage can be usually found on the label of the drink. It tells the percentage of ethyl alcohol or ethanol content in the beverage.
