To calculate the Alcohol by Volume (ABV), subtract the Final Gravity (FG) from the Original Gravity (OG), and then multiply the result by 131.25. This gives you the percentage of alcohol in the beverage.

The **Alcohol Per Volume Calculator** is a useful tool for determining the alcohol content in beverages, typically used by brewers and distillers to measure the Alcohol by Volume (ABV) percentage. It helps to know the strength of a drink based on the initial and final specific gravity readings.

**Formula:**

The formula to calculate Alcohol By Volume (ABV) is:

$ABV = (OG – FG) \times 131.25$

Where:

**OG**= Original Gravity (before fermentation)**FG**= Final Gravity (after fermentation)**ABV**= Alcohol by Volume percentage

**How to Calculate ?**

**Measure Original Gravity (OG):**This is the density of the liquid before fermentation starts.**Measure Final Gravity (FG):**This is the density of the liquid after fermentation ends.- Subtract the Final Gravity from the Original Gravity.
- Multiply the result by 131.25 to get the Alcohol By Volume (ABV) percentage.

**Solved Calculations**

**Example 1:**

Given:

- Original Gravity (OG) = 1.080
- Final Gravity (FG) = 1.020

Variable | Value |
---|---|

Original Gravity | 1.080 |

Final Gravity | 1.020 |

$ABV = (1.080 – 1.020) \times 131.25 = 0.060 \times 131.25 = 7.875$

**Answer:** The Alcohol By Volume (ABV) is 7.88%.

**Example 2:**

Given:

- Original Gravity (OG) = 1.050
- Final Gravity (FG) = 1.010

Variable | Value |
---|---|

Original Gravity | 1.050 |

Final Gravity | 1.010 |

$ABV = (1.050 – 1.010) \times 131.25 = 0.040 \times 131.25 = 5.25$

**Answer:** The Alcohol By Volume (ABV) is 5.25%.

**What is Alcohol Per Volume Calculator ?**

The Alcohol Per Volume Calculator is a useful tool for anyone looking to determine the alcohol content in beverages. This calculator helps you find the percentage of alcohol based on volume, which is crucial for understanding what you’re consuming. It can be especially handy for measuring drinks like cocktails, beers, or spirits.

To use the calculator, simply input the volume of the beverage and its alcohol by volume (ABV) percentage. The calculator will then provide you with the total amount of alcohol in that drink. This can help you keep track of your alcohol intake, especially if you’re watching your consumption for health reasons.

Understanding alcohol per volume is important for responsible drinking. For example, knowing that a beverage contains 5% alcohol by volume means that in every 100 mL of that drink, there are 5 mL of pure alcohol. With tools like the Alcohol Per Volume Calculator, you can make informed decisions about how much you drink, ensuring you enjoy responsibly.
