What is a unit?


Alcohol is available in many different strengths depending on how it is produced.

The amount of alcohol in a drink is measured in units. One unit is equivalent to 10 ml or 8g of pure alcohol. The size and strength of your drink will determine the number of units it contains.

It’s all very well talking in units, but what does this really mean when you’re on a night out at the pub or over dinner at home? The size and strength of your drink will determine the number of units it contains. Unfortunately it’s not as simple as one drink, one unit.

A glass of wine could be 1to 3+ units depending on the size of the glass and type of wine.

When people drink at home, they tend to pour measures that are larger than you get in their local pub. So you could be regularly drinking far more than you think.

Recommended daily limits:


Men: 3 to 4 units;
Women: 2 to 3 units

1 pint or a 175cl glass of wine
is about 2.3 units!
