"A unit of alcohol is 8 grams by weight or 10 ml by volume. All containers of alcoholic drinks in the UK must have the percentage alcohol by volume (ABV) printed on the label and some may also have the number of units contained in the bottle or can." "You can work out the number of units in a bottle of beer or wine for yourself Number of units = volume of drink in container (ml) x ABV ÷ 1000 A 500ml bottle beer with 5% alcohol by volume would contain 500ml x 5% ABV ÷ 1000 = 2.5 units Or 750ml bottle wine with 13% alcohol by volume would contain 750ml x 13% ABV ÷ 1000 = 9.75 units" Source: http://www.disen.org/nutrition/pages-to-edit/ALCOHOLANDEXERCISE.htm Further information: "To work out how many units of alcohol you are drinking you may need to convert pints to litres, and you will also need to know the '% abv' of the different types of alcohol you are drinking. As a rough approximation, 2 pints = just over 1 litre (1.13 litres to be precise)." http://www.dryoutnow.com/alcohol-help/alcohol-help_a107.shtml
