Estimated alcohol units: 2.95 (2.95 units per serving)

This follows the NHS alcohol-units formula: drink volume in millilitres multiplied by ABV and divided by 1,000.

  • →Double-check the serving size because bottle, can, and glass volumes can vary more than people expect.

About Alcohol Units Calculator

Alcohol Units Calculator helps you work through the main numbers for this topic quickly with a simple input flow and an instant result.

Use the calculator result as a practical starting point, then review the explanation and assumptions on the page if you want more context.

UK alcohol-unit formula

Multiply drink volume in millilitres by ABV, then divide by 1,000. One 568 ml serving at 5.2% ABV contains 2.9536 units, shown as 2.95. A 0% drink contains zero alcohol units.

NHS low-risk guidance advises no more than 14 units a week on a regular basis, spread over 3 or more days. A unit total is not a driving-safety decision or an estimate of blood alcohol.

Example

Example: one 568 ml pint at 5.2% ABV contains 2.95 UK units.

Assumptions

  • Units per serving = volume in millilitres x ABV percentage / 1,000; total units multiply this by the whole-number serving count.
  • One UK unit is 10 ml or 8 g of pure alcohol; 0% ABV correctly returns zero units.
  • This does not calculate calories, blood alcohol, impairment, medical risk or whether it is safe or legal to drive.

Source basis

  • UK-focused calculator flow
  • Structured input validation
  • Instant result breakdowns
