The UK measures alcohol in units to track total amount consumption, as it’s not easy to track with percentage in volume. A unit is 10 ml of pure alcohol, and cans/bottles/etc have the total units printed. That way it’s supposed to be easier to track how much alcohol you drink e.g. if you drink a beer, then a wine - now that’s 4 units.
I’m not British so I’m not used to units, but at least that’s the theory.
