Quick answer: Alcohol Unit Calculator
UK units from volume × ABV, NHS 14-unit weekly benchmark, rough sober-time and kcal from ethanol.
Example: Two pints at 5% might exceed several units each - stacked across a week vs the 14-unit guidance line.
Calculations follow the documented formula on this page; rounding and input units can change the last digit—treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
What this calculator does
- Alcohol Unit Calculator
- UK units, NHS weekly guide, calories, and rough metabolism time.
Pure alcohol ml drives units; metabolism hours are illustrative because liver health and food intake shift clearance.
Estimate standard drink units from volume, ABV%, and quantity; compare to 14 UK units/week guidance and approximate kcal and clearance time.
Inputs on this page: Drink type (sets typical volume per drink), ABV %, Number of drinks. Assumptions stay visible so you can reproduce the figure elsewhere.
When to use it
- Use Alcohol Unit Calculator when you need a transparent alcohol units calculator answer before you commit numbers to a spreadsheet, invoice, or conversation.
- Reach for it when you already know (or can estimate) Drink type (sets typical volume per drink) and want the dependent result without rebuilding the formula by hand.
- Skip it when you need certified advice, signed-off payroll, or a lender’s official quote—those require the primary institution’s systems.
Key takeaways
- Standard drinks differ in the US - don’t mix jurisdiction advice.
- Driving limits are legal, not metabolic; use taxis after drinking.
- Seek help if cutting down feels impossible - clinical support works.
How to use this tool
- 1Choose drink style, enter ABV%, and how many of that drink.
- 2Review total units, calories, and rough hours to clear one unit.
- 3Low-risk drinking varies by person - when in doubt, drink less.

Key formula explained
How the calculation works
The Formula
UK units = pure alcohol ml ÷ 10; kcal from ethanol mass × 7- Drink type (sets typical volume per drink): the value you enter for drink type.
- ABV %: the value you enter for abv.
- Number of drinks: the value you enter for quantity.
