Limitations upon Use
This calculator is based upon a formula developed by the Department of Transportation (DoT) in the United States, however a person's blood-alcohol level is the result of a complex interaction of weight, gender, alcohol consumed, and time.  The same person will often register different results for the same consumption depending upon numerous factors including meals eaten and type of alcohol drunk. This calculator can only give a very rough guide and actual results on a Breathalyzer WILL vary considerably depending upon the individual and the circumstances of the test.  In particular the time taken to absorb the alcohol into the body can vary dramatically and therefore the level may rise as well as fall after the last drink is consumed. Only a Blood Test can accurately calculate the level of alcohol in the blood at any given time.
 

The calculation assumes that one drink equals approx. 1 shot of 40% spirit, 125ml of 11% wine, or 1/2 pint 4.5% beer. Result is given as if tested 20 minutes after the last drink, however note that in some people it can take up to 2 hours to reach peak levels. Intoxication levels can RISE as well as fall for some time after your last drink. ANY alcohol in the Blood WILL impair your judgement and may be dangerous
