<P> Different countries define standard drinks differently . For example, in Australia, a standard drink contains 10 grams of alcohol, but in Japan, it contains nearly 20 grams . In addition, a standard drink is often different from normal serving size in the country in which it is served . </P> <P> Labeling is usually required to give an indication of alcoholic content of a serving . Australia requires that "the label on a package of an alcoholic beverage must include a statement of the number of standard drinks in the package". </P> <P> The term "standard drink" was used in the United Kingdom in the first guidelines (1984) that published "safe limits" for drinking, but this was replaced by reference to units of alcohol in the 1987 guidelines and that term has been used in all subsequent UK guidance . A unit of alcohol is defined there as 10 millilitres (8 grams) of pure alcohol . This definition is independent of the strength (% ABV) and amount (volume) of any individual alcoholic beverage . The number of units of alcohol in a bottle or can (and, optionally, the number of units in a typical serving) are indicated on the drink container . Typical servings deliver 1--3 units of alcohol . </P> <P> The amount of alcohol is stated in the table in both grams (g) and millilitres (mL). The number of standard drinks contained in 500 mL (16.9 fluid ounces) of beer of 4.5% ABV (a typical large drink of beer) is stated for comparison . </P>
