A unit of alcohol can be calculated using the following formula:
[Volume (mls) x Alcohol by Volume ABV (%)] / 1000

For example, 250ml of 12% ABV wine will be:
[250 x 12 = 3000] / 1000 = 3 units.
For those not that keen on formulas, please use the alcohol unit calculator below, which will do the math for you.

Alternatively, take the Alcohol Test, where you can calculate the amount of units and calories you drink in a typical day AND see how risky your drinking is. Or, why not download our free DrinkCoach App, where you can track the amount of units, calories and cost of what you are drinking over a longer time period.
