Have you ever wondered what the exact number of units in any given alcoholic drink is?

Here is a sum to work it out.

Multiply the volume of drink (in ml) by the alcoholic strength by volume (ABV) and divide by 1000.

440ml can of beer
ABV 5%
Divide by 1000

440 x 5 = 2200 / 1000 = 2.2 units

Know Your Units
The NHS recommends that:

Men should not regularly drink more than three to four units of alcohol per day.
Women should not regularly drink more than two to three units of alcohol per day.

You should also take a break for 48 hours after a heavy session to let your body recover.


The limits are lower for women because women's bodies have a higher ratio of fat to water than men, making them less able to dilute alcohol in the body and they do not process alcohol as effectively.
