English term (edited): standard drinks.

What is a standard drink?
A standard drink is any drink that contains approximately 10 grams of alcohol. Use the label on the bottle, can or cask to find out how many standard drinks are inside the container.
How much are you really drinking?
It can be difficult to work out if your drink is a standard drink because glass sizes are not the same in different drink venues, and different types of drinks contain different proportions of alcohol per volume.

A standard drink is fixed measure of pure beverage alcohol used in many countries. They are usually expressed as a measure of beer, wine or spirits for simplicity. The definition of a standard drink can vary significantly from country to country, from as low as 10 mL (7.9 g) of alcohol in the UK to as high as 25 mL (19.75 g) in Japan. The value of one standard drink does not necessarily reflect a typical serving size in its country. For example, a pint of ale served in Britain (at five percent alcohol by volume) would be defined as 2.84 standard drinks.
