What Is A Unit Of Alcohol?

According to the NHS, one unit of alcohol is equivalent to 10ml of pure alcohol. In terms of standard drinks measurements, there are approximately:

• 2 units in one pint of low strength beer or cider (3.6%)

• 3 units in one pint of high strength beer or cider (5.2%)

• 2.1 units in one 175ml glass of average strength wine (12%)

• 3 units in one 250ml glass of average strength wine (12%)

• 1 unit in a single measure of spirit (25ml)

However, this is not an exact science and many other factors can affect how quickly or slowly your body breaks down alcohol. These include:

• Weight

• Gender

• Age

• Metabolism

• Stress levels

• Medication you may be taking

• Type and strength of the alcohol consumed
