WHAT IS A STANDARD DRINK?
In Australia a 'Standard Drink' is one that contains 10 grams of alcohol. Other countries have different measures which can range from 13.5 grams in Canada to 8 grams in the UK.
Most beverages are labeled with their percent alcohol by volume (i.e. 5%), so to calculate how many standard drinks a particular beverage serving represents you find out how much alcohol is in the drink, multiply by 0.79 (the density of alcohol and needed to convert a volumetric percentage to grams) and then calculate how many standard drinks that represents.
Examples:
A can of premix spirits is 1.2 to 1.5 standard drinks
A full strength stubby of beer is 1.5 standard drinks
An Alcoholic Soda is 1.0 to 1.2 standard drinks
A bottle of wine (750ml) is 7.5 standard drinks
A bottle of spirits (700ml) is 22 standard drinks
