How to calculate units of alcohol
We’re often asked how many units of alcohol are in a particular drink. You’ll be pleased to hear that it’s straightforward enough to calculate.
Multiply the alcohol by volume (abv) by the volume of drink in litres (one standard bottle of wine would be 0.75 litres for example, a standard glass would be 0.125, etc).
So, for example, drinking one glass of wine at 13.5% alcohol would be 0.125 x 13.5 = 1.7 units.
Or, a whole bottle of wine at 14% would be 0.75 x 14 = 10.5 units.
Or a pint of beer (0.568 litres) at 4.5% = 2.6 units.
Easy and really, really helpful…
And please don’t forget the Government’s recommended maximum limit is 3 -4 units per day for men and 2 – 3 units per day for women. And in some circumstances such as driving, operating machinery and pregnancy, it is better not to drink at all.
