Alcohol affects men and women differently. In order to give you the most accurate results, we need to know your gender.

Male Female

The government advises that people should not regularly drink more than the daily unit guidelines of 3-4 units of alcohol for men (equivalent to a pint and a half of 4% beer) and 2-3 units of alcohol for women (equivalent to a 175 ml glass of wine). ‘Regularly’ means drinking every day or most days of the week.

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. Learn more about the calories in alcohol.

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%).
