Why?

This tool is only an estimate - you must always ensure you are sober before driving, and we do not accept any responsibility for action taken on the basis of this calculator.

An average liver can process approximately 1 unit of alcohol per hour. This means that if you drink 12 units, it'll take you roughly 12 hours to fully sober up. Our calculator uses an average for drinks size and strength to give you a rough time for sobriety.

However many things can alter your rate of liver metabolism, so you should be very careful. Known factors for affecting this rate include being young, old, Asian, a heavy drinker or on medication. Also, if you have any liver disease, are overweight or underweight, along with countless other details, this calculator will be inaccurate.
