The rough guideline normally given is that one unit (around 10ml) is metabolised per hour, however this varies from person to person.
It depends why you are asking, if you are asking for an alcohol blood test then you should wait at least 24 hours. If you are asking for reasons such as being legal to drive then you can calculate the time based on 1 unit per hour, then add a couple of hours to be safer.
The human body will pretty much always contain some alcohol due to small amounts being present in a variety of sources including mouthwash, most fruit (small amounts of the sugars will be fermented) and others.

it stays in the system for approximately 24 hours and it can exceed in case the dose is higher than the permissible normal limits.
