Calculate UK alcohol units
Estimated UK alcohol units1.6Using 8 g pure ethanol per UK alcohol unit
EtG context: the conversion improves the alcohol-dose estimate. It does not produce a measured EtG level or guarantee a urine-test result.
United Kingdom drink examples
| Beverage | Serving | Approximate result |
|---|---|---|
| Lager | 568 mL pint at 4% | About 2.3 UK units |
| Wine | 175 mL at 12% | About 2.1 UK units |
| Spirits | 25 mL at 40% | About 1 UK unit |
What is genuinely country-specific?
- The standard UK formula is volume in mL × ABV ÷ 1,000.
- A UK unit contains less ethanol than a U.S., Canadian, or Australian standard drink.
- Convert units before entering a U.S.-standard-drink count in the main EtG calculator.
Official definition
The definition and examples on this page are based on GOV.UK alcohol guidance. Local definitions describe ethanol quantity; laboratory EtG testing policies can still vary by laboratory, program, and test method.
Use the converted result
Enter the converted amount into the EtG urine calculator, calculate exact elapsed time with the EtG timeline tool, and read the EtG test FAQ before interpreting the range.
