**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):

$ABV=(7.46OG−FG )×100$

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.

$ABV=(7.46− )×100$

$ABV=(7.460.045 )×100$

$ABV≈0.602$

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

**FAQs**

**Q: What is the purpose of calculating alcohol percentage in beer?**

A: Knowing the alcohol content helps brewers control the fermentation process and allows consumers to make informed choices about their alcohol intake.
