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 standard drinks. A single standard drink consists of 0.6 fl oz/14g of alcohol. With this calculator you’re able to select the drinks you have consumed and determine the amount of standard drinks your body has absorbed.

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 States. To help estimate your BAC level, we provide a US BAC Calculator.
