What's a unit?
A UK unit is 10ml or 8 grams of pure alcohol. The number of units in a drink depends on what you're drinking - how strong it is and how much there is. You may have seen examples of drinks that contain one unit, but these examples are often out of date, for instance:
Half a pint of 3.5% beer/lager/cider
BUT many continental lagers are closer to 5% while extra strong lagers can be as strong as 9%!
One small (125 ml) glass of wine at 9% is one unit
BUT who uses small glasses? Certainly not pubs and probably not at home either. Plus most wines are now about 11-13%.
A 25ml pub measure of spirit at 40% is one unit
BUT some pubs now serve 35ml as standard. Plus other pubs will serve you a double unless you specify otherwise.
How Many units am i allowed to drink and still Drive ?
The current legal limit for driving in the U.K. is 80milligrams of alcohol per 100millitres of blood, 35 micrograms of alcohol in 100 ml of breath or 107 milligrams of alcohol per 100ml of urine.
The legal drink drive limit can't be safely converted into a certain number of units, as everyone absorbs alcohol into the blood stream at different rates. However, an average man (12-13 stone) should consume no more than 4 units and an average woman (9-10 stone) should consume no more than 3 units. If you are particularly small or have not eaten these figures should be reduced.
There you have it, Basically yo need to be a scientist to calclate if yo are safe to drive after a beer or two....
