How long do alcohol units stay in system?

[starfish4]

Fancy having a couple of glasses of wine tonight (250ml), roughly between 8-10.30pm. Won't drink after as I want a clear head for work. Does anyone know how long it'll take to leave my system before driving (thinking I don't want it in my system for driving to work)?

If it's 2x 250 ml That's approx 4 units so approx 4 hours per unit. So by 12.30am- 2.30am you should have processed the alcohol.

It depends on % of wine and how many units per 125ml. And it depends on your metabolism.

Depends on the % of the wine but 250ml can be 3 units so approx 6 hours for 2 glasses to be out of your system
Tomorrow morning should be fine

There's a morning after calculator. Think this is it

Ignore my message. I thought it was 1 hour let unit. I stand corrected.
