What are Alcohol Units?

Keeping track of the amount of alcohol you have consumed can be tricky. The most common way to achieve this is to express the amount of pure alcohol in your drinks as alcohol units. A single alcohol unit consists of 10.139ml/8g of alcohol. With this calculator you’re able to select the drinks you have consumed and determine the amount of alcohol units your body has absorbed. For further detailed information view our alcohol unit guidelines.

An important step after calculating the amount of alcohol you have consumed is to determine the length of time it will take to exit your system. This is especially important if you plan to drive a vehicle and avoid being over the legal limit, which is a 0.08% BAC level in the United Kingdom. To help estimate your BAC level, we provide a UK BAC Calculator.
