Just enter your Original Gravity (OG) and Final Gravity (FG) in the fields to the left to instantly calculate your ABV percentage.

To make adjustments to your gravity measurements please refer to this chart to adjust your measurements accordingly

Formula used for ABV:
ABV =(76.08 * (OG – FG) / (1.775 – OG)) * (FG / 0.794)

Formula used for Apparent Attenuation
Attenuation% = ((OG-FG)/(OG-1))x100
