How many units of alcohol in a pint of beer ? You know the answer thanks to PerfectDraft. Enjoying a perfectly chilled pint from your PerfectDraft system combines the pleasure of a pub-quality pour with the comfort of home. A common question among beer enthusiasts is: how many units are in a pint of beer? Understanding this helps you enjoy your drink responsibly while maintaining control over your alcohol intake.

Knowing the unit content of your beer allows you to make informed decisions and enjoy every pour as a deliberate, relaxed experience rather than guesswork.

How many units are in a pint of beer ?

In the UK, one unit of alcohol equals 10 ml of pure alcohol. A standard pint (568 ml) contains a number of units depending on its Alcohol by Volume (ABV). The formula is simple:

Units = (Volume in ml × ABV) ÷ 1000

For example:

  • 4% ABV beer: 2.3 units per pint
  • 5% ABV beer:  2.8 units per pint

This shows how even a small increase in ABV can significantly impact the total number of units in your pint. Checking the ABV on your PerfectDraft keg is the easiest way to stay informed.

  • Glass size: Larger servings contain more alcohol units.
  • Beer style: Stronger beers like IPAs or stouts often have higher unit counts.
