How many units in a glass of wine
A 175 ml medium glass of 13% wine is 2.3 UK units. A 250 ml large glass is 3.3. The word "glass" is not a unit.
Two large 13% glasses are 6.5 UK units. That is already half of a 14-unit UK week, before the rest of the week starts.
175 ml, the UK medium
This is the default in many UK pubs when you do not specify. It is larger than a French 12.5 cl (125 ml) restaurant pour.

Common questions
How many units in a 175 ml glass of wine?
At 13%, 2.3 UK units (175 × 13 ÷ 1000 = 2.275). About 1.8 French verres standards.
How many units in a 250 ml large glass of wine?
At 13%, 3.3 UK units (250 × 13 ÷ 1000 = 3.25). About 2.6 French verres. Two large glasses are already 6.5 UK units.
Is a pub glass 175 ml?
In the UK, 175 ml is the usual medium and 250 ml the large. 125 ml is the small, closer to a French 12.5 cl serve. Ask which one was poured. The menu often does not.
Why not count glasses instead of units?
Because 125 ml of 12% and 250 ml of 14% are both "a glass" and not the same alcohol. Count millilitres and ABV, or the week is fiction.
