A typical pint of beer contains about 2 to 3 alcohol units , but it depends on the strength (ABV) of the beer and the pint size used in the UK.

Quick Scoop

In the UK, a pint is 568 ml. To work out units, the standard formula is:
units = strength (ABV) × volume (ml) ÷ 1,000.

Common examples (UK pint – 568 ml)

  • Pint of lower-strength lager/beer/cider at 3.6% ABV ≈ 2 units.
  • Pint of standard-strength lager/ale around 4% ABV ≈ 2.2–2.3 units.
  • Pint of 4.5% ABV beer ≈ 2.5 units.
  • Pint of stronger lager (around 5–5.2% ABV) ≈ 2.8–3 units.

So when people ask “how many units in a pint of beer?” , they usually mean:

  • Around 2 units for a weaker pint.
  • Around 2.3–2.5 units for “normal” 4–4.5% beer.
  • Around 3 units for a strong pint.

Simple rule of thumb

  • Use the formula: ABV × 0.568 × 2 (rough mental shortcut) – for example, 4% × 0.568 ≈ 2.3 units.
  • Or remember: most pub-strength pints sit somewhere between 2 and 3 units.
