Do equal alcohol amounts mean equal BAC?
No. This comparison concerns the drinks only. The same alcohol amount does not determine the same BAC for different people or drinking schedules. Use the BAC calculator for a personal estimate.
How much pure alcohol is in a serving?
| Volume | Alcohol strength | Pure alcohol |
|---|---|---|
| 12 US fl oz | 5% | ≈ 0.6 US fl oz |
| 5 US fl oz | 12% | ≈ 0.6 US fl oz |
A 12 US fl oz drink at 5% contains 0.6 US fl oz of pure alcohol — about one US standard drink. Multiply the serving volume by the alcohol percentage and divide by 100. This is the alcohol in the drink, not your blood alcohol level.
