Calories in alcohol

The alcohol unit calculator shows you the number of calories in the alcohol you have consumed. Many people are very surprised by the number of calories in alcoholic drinks - it is easy to make the mistake of thinking that drinks are calorie-free.

Being high in sugar means alcohol can contain lots of calories - seven calories a gram in fact. That's almost as must as pure fat. Calories from alcohol are 'empty calories', they have no nutritional value.

What is an alcohol unit?

One alcohol unit is measured as 10ml or 8g of pure alcohol. This equals one 25ml single measure of whisky (ABV 40%), or a third of a pint of beer (ABV 5-6%) or half a standard (175ml) glass of red wine (ABV 12%).
