Formula and Calculation
\n
The standard formula to calculate ABV from gravity readings is:
\n
(OG – FG) × 131.25 = ABV %
\n
Where:
\n
| Variable | Meaning | Unit |
|---|---|---|
| OG | Original Gravity | Specific Gravity |
| FG | Final Gravity | Specific Gravity |
| 131.25 | Conversion Factor | Constant |
