One unit of alcohol is defined as 10 ml of pure alcohol.
That's about 8 gm (I think).
In the UK the strength of an alcoholic drink is given as Alcohol by Volume, as a percentage.
Beer is typically about 5%.
To work out the unit you multiply the serving size in liters by the ABV number.
A 330 ml bottle of beer at 5% = 0.33 * 5 = 1.65 units. (The bottle would probably say 1.7 units.)
The US uses a different amount of alcohol for their standard drink. I think they use 12 gm of pure alcohol.
