Frequently asked questions
- What counts as one standard drink?
- In the US, one standard drink contains 14 g of pure alcohol: 12 oz regular beer (5%), 5 oz wine (12%), or 1.5 oz spirits (40%). UK units are different (8 g/unit).
- What is the legal driving limit?
- Limits vary by country. In the US most states use 0.08%; in the UK it is 0.08% in England/Wales and 0.05% in Scotland; in many EU countries 0.05%. There is no safe amount of alcohol to drive.
- How does body weight affect BAC?
- Higher body weight means more body water to dilute alcohol, so a heavier person will typically have a lower BAC for the same number of drinks. The Widmark formula captures this via the weight term.
