Just enter your Original Gravity (OG) and Final Gravity (FG) in the fields to the left to instantly calculate your ABV percentage.
PLEASE NOTE: This calculator assumes you have made all temperature corrections to your measurements beforehand and gives an approximate ABV value.
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
