How much is one unit?
It’s all well and good talking about milligrams of alcohol in your blood, but what does that look like in your glass? How much is one unit?
Well one unit is 8g, or 10ml if you prefer, of pure alcohol. There are approximately:
- 2.1 units in a 175ml standard glass of wine.
- 3 units in a large glass of wine.
- 2 units in a pint of normal lager, cider or beer.
- 3 units in a pint of high strength lager and cider.
- 1 unit in a measure of spirits.
So your body may take 3 hours, approximately, to break down a pint of high strength lager. But again, it can vary from person to person.
If you have a number of drinks during the course of the evening then you can still be over the legal drink drive limit the next day, so you need to be mindful if you know you have to drive in the morning and plan an alternative to driving.
