As little as possible! The amount of deaths on the roads each year should tell you that drink + drive = bad news.

1 unit = 1/2 pint of ordinary strength beer, 1 single measure of spirits (40% alcohol or less), 1 small glass of wine or 1 single measure of fortified wine.
The driving limit is measured by blood alcohol content though rather than the amount of units you've had, it's currently 80mg of alcohol per 100ml of blood. Unfortunately, the amount of alcohol that gets absorbed into the blood varies from person to person depending on their sex, body mass, how much food was in the stomach when the alcohol was drank etc.
Just don't bother drinking at all if you're going to drive, it's not worth the risk from the point of view of both safety and the law.

Formula
----------
A unit of alcohol is equivalent to 10 millilitres (or approximately 8 grams) of pure ethanol, the active chemical ingredient in alcoholic beverages.
The number of units of alcohol in a drink can be determined by multiplying the volume of the drink (in millilitres) by its percentage ABV, and dividing by 1000.
Thus a pint (568ml) of beer at 4% ABV contains 2.3 units.
Quantities
-------------
As a rough guide:
*A glass of wine or sherry, a single measure of spirits and a half pint of beer each contain about one unit, or 8 g (0.25 oz) of alcohol.
*A large glass of red or white wine or half a pint of cider contains about 12g (3/8oz), or one and a half units.
*However strong lager may contain as much as two units per half pint.
Limits
-------
Since 1995 the UK government has advised that regular consumption of between three and four units a day for men and between two and three units a day for women would not pose significant health risks, but that consistently drinking four or more units a day (men) or three or more units a day (women) is not advisable. The difference between genders is given due to the (typically) lower weight and water-to-body-mass-ratio of women.
