Formula
- Alcohol By Volume (ABV) Calculator calculates its result from Original Gravity (OG), Final Gravity (FG). It uses the formula ABV % = (OG − FG) × 131.25. Change any input to recalculate the result instantly.
- The main inputs are Original Gravity, Final Gravity. Enter them in the units and format shown in the calculator.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Alcohol By Volume (ABV)
- Original Gravity: 1.05 OG
- Final Gravity: 1.01 FG
Using Original Gravity (OG) = 1.05, Final Gravity (FG) = 1.01, the calculated result is 5.25.
