This tool calculates the alcohol by volume (ABV) based on the original and final gravity readings you provide.
ABV from Gravity Calculator
This calculator helps you determine the Alcohol by Volume (ABV) from the original gravity (OG) and final gravity (FG) of your brew. You can use the box below to input these values and the calculator will give you results using different calculation methods.
How to Use
- Input your original gravity (e.g., 1.050) in the “Original Gravity (OG)” field.
- Input your final gravity (e.g., 1.010) in the “Final Gravity (FG)” field.
- Click the “Calculate” button to see the results.
Explanation of Results
The calculator provides three different methods to determine the ABV:
- Standard Formula: Uses the formula ABV = (OG – FG) * 131.25.
- Alternative Formula: An alternative method calculated as ABV = 76.08 * (OG – FG) / (1.775 – OG) * (FG / 0.794).
- Simple Formula: A simpler approximation calculated as ABV = (OG – FG) * 105.61 / FG.
Limitations
Note that these formulas provide estimates and may vary slightly in accuracy depending on numerous factors including but not limited to the specific conditions of fermentation, yeast type, and measurement precision. Always ensure proper calibration and use professional lab equipment for the most accurate results.
