A standard drink is a notional drink that contains a specified amount of pure alcohol (ethanol). The standard drink is used in many countries to quantify alcohol intake. It is usually expressed as a certain measure of beer, wine, or spirits. One standard drink always contains the same amount of alcohol regardless of the container size or the type of alcoholic beverage, but does not necessarily correspond to the typical serving size in the country in which it is served.
The standard drink varies significantly from country to country. For example, it is 7.62 ml (6 grams) of alcohol in Austria, but in Japan it is 25 ml (19.75 grams).
In the United Kingdom, there is a system of units of alcohol which serves as a guideline for alcohol consumption. A single unit of alcohol is defined as 10 ml. The number of units present in a typical drink is printed on bottles. The system is intended as an aid to people who are regulating the amount of alcohol they drink; it is not used to determine serving sizes.
In the United States, the standard drink contains 0.6 US fluid ounces (18 ml) of alcohol. This is approximately the amount of alcohol in a 12-US-fluid-ounce (350 ml) glass of 5% ABV beer, a 5-US-fluid-ounce (150 ml) glass of 12% ABV wine, or a 1.5-US-fluid-ounce (44 ml) glass of a 40% ABV (80 proof) spirit.
In New Zealand, the standard drink is calculated by the amount of drink in litres (Vol) x Percent by volume of alcohol (%) x Density of ethanol at room temperature (0.789)
