Frequently asked questions
- What is an alcohol unit?
- A UK measure: 10 ml or 8 g of pure alcohol. A 350 ml beer at 5% is about 1.7 units.
- What is a US standard drink?
- 14 g of pure alcohol - roughly a 12 oz beer at 5%, 5 oz of wine at 12%, or 1.5 oz of spirits at 40%.
- How long until alcohol leaves my system?
- About one standard drink per hour on average. The estimate shown uses 7.5 g per hour as the metabolic rate.
- Does the type of drink matter?
- Only volume and ABV matter for the calculation. Carbonation and food change absorption speed, not total alcohol.
