A pint of beer in the UK is typically 568 ml, and the number of alcohol units in a pint depends on the beer's alcohol by volume (ABV) percentage. The formula to calculate alcohol units is:
Units=ABV×Volume in ml1000\text{Units}=\frac{\text{ABV}\times \text{Volume in ml}}{1000}Units=1000ABV×Volume in ml
For common ABV values in beer:
- A pint of 3.4% ABV beer has about 1.9 units.
- A pint of 4.0% ABV beer has about 2.3 units.
- A pint of 5.0% ABV beer has about 2.8 units.
- A pint of 5.2% ABV beer has about 3 units.
- Stronger beers (e.g., 9% ABV) can have over 5 units in a pint.
Typical average-strength beer (around 4-5% ABV) contains roughly 2.3 to 2.8 units per pint.
