Where I live, and it seems in most places in the world, a standard drink is 10g of alcohol.
> The definition of what constitutes a standard drink varies very widely between countries,[2] with what each country defines as the amount of pure alcohol in a standard drink ranging from 8 to 20 grams.
> The sample questionnaire form for the World Health Organization's Alcohol Use Disorders Identification Test (AUDIT) uses 10 g (0.35 oz),[3] and this definition has been adopted by more countries than any other amount.
