Units are a form of measurement used to represent the amount of alcohol in a drink. One unit of alcohol is roughly how much an adult’s body can process in an hour and is equivalent to 10ml/8g of pure alcohol.


Government guidelines on alcohol suggest that men do not regularly drink more than 3-4 units of alcohol a day, and for women it’s slightly lower at 2-3 units a day. People are also advised to take a break of at least 48 hours if they have taken part in heavy drinking.


It is important for people to watch what they are drinking very carefully and try to manage their levels of drinking and their relationship with alcohol but it can be hard to tell how many units are in different types of alcoholic drink.


Use the NHS Choices alcohol tracker to find out how many units there are in a single drink or in a number of drinks.
