Alcohol unit calculator
You can use our alcohol units calculator to find out how many units are in your drink. The alcohol units we show are intended as a rough guide only, and are not a substitute for common sense.
If you're driving, don't drink. If you're drinking, don't drive.

This is the recommended amount of no more than 14 units per week.
How many units can you drink and drive after?
Despite the legal limits there's simply no hard and fast rule. The rate at which your body absorbs alcohol depends on a number of factors, such as your sex, weight, what you’ve eaten and when, and your stress levels. You can get more info on this at GOV.UK.
Because alcohol affects each person differently, there's no fool proof way of drinking and staying under the limit, that’s why you should never drive after any alcoholic drink.
One person may be okay to drive after one or two drinks, while another is over the drink-drive limit after only one. Don’t forget you could also be well over the limit the next day after a night out, and if you’ve been drinking you should never sleep in your car, because the police view is that you’re still technically in control of the vehicle even if the engine is off. So if the police find you, you could be breathalysed and charged just as if you were driving.
You can get a rough estimate of your blood alcohol content (BAC) level using our morning after calculator.
We'll say it again - if you're driving, then don’t drink any alcohol.
