Beer Alcohol Percentage Calculator

Introduction

Calculating the alcohol percentage in beer can be essential for various purposes, from brewing your own beer to understanding the strength of the beverage you’re consuming. In this article, we’ll introduce you to a simple and efficient Beer Alcohol Percentage Calculator using HTML and JavaScript.

How to Use

To use the Beer Alcohol Percentage Calculator, follow these steps:

Input the original gravity (OG) and final gravity (FG) values into the respective fields.
Click the “Calculate” button to obtain the accurate alcohol percentage in your beer.

Formula

The formula used in the calculator is based on the standard formula for alcohol by volume (ABV):

$A B V = (7.46 OG - FG) \times 100$

Where:

$OG$ is the original gravity.
$FG$ is the final gravity.
7.46 is a constant factor.

Example

Suppose you have an original gravity ( $OG$ ) of 1.060 and a final gravity ( $FG$ ) of 1.015.

$A B V = (7.46 1.060 - 1.015) \times 100$

$A B V = (7.46 0.045) \times 100$

$A B V \approx 0.602$

So, the Alcohol By Volume (ABV) is approximately 6.02%.
