How to Calculate Alcohol Content
What is Alcohol Content?
An alcohol content calculator computes ABV (Alcohol By Volume) for home-brewed beer or wine using original gravity and final gravity measurements. It also calculates the number of units in a drink for health guidance.
Step-by-Step Guide
- 1Simple ABV: (OG − FG) / 7.46 (for beer, using SG points)
- 2More accurate: ABV = 76.08 × (OG − FG) / (1.775 − OG) × FG / 0.794
- 3Units in a drink: volume (ml) × ABV (%) / 1,000
Worked Examples
Input
OG 1.060 · FG 1.010
Result
ABV ≈ 6.6%
(1.060−1.010)/7.46×1000 = 6.7
Input
500ml beer at 5% ABV
Result
2.5 units
500×5/1000=2.5
