Calculate standard drinks
Estimated standard drinks0.9Using 14 g pure ethanol per standard drink
EtG context: the conversion improves the alcohol-dose estimate. It does not produce a measured EtG level or guarantee a urine-test result.
United States drink examples
| Beverage | Serving | Approximate result |
|---|---|---|
| Regular beer | 12 fl oz / 355 mL at 5% | About 1 U.S. standard drink |
| Table wine | 5 fl oz / 148 mL at 12% | About 1 U.S. standard drink |
| Distilled spirits | 1.5 fl oz / 44 mL at 40% | About 1 U.S. standard drink |
What is genuinely country-specific?
- U.S. serving examples use fluid ounces, but the calculator accepts millilitres for a consistent international formula.
- A customary pour can contain more or less than one standard drink.
- The standard-drink result estimates ethanol amount; it does not predict impairment or a urine EtG concentration.
Official definition
The definition and examples on this page are based on National Institute on Alcohol Abuse and Alcoholism. 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.
