What are units of alcohol?
Units are confusing and you might be thinking I don’t really care about units in my
drinks. Well if you are under 18 there are no guidelines for you to follow, but this
information might help you when you get old, it’s like that Science stuff you learn at
school which you think you will never need to know!
You can work out how many units there are in any drink by multiplying the total volume of a
drink (in ml) by its ABV (which is measured as a percentage) and dividing the
result by 1,000. See you are even doing Math’s revision!
Strength (ABV) x Volume (ml) ÷ 1,000 = units.
For example, to work out the number of units in a pint (568ml) of strong lager (ABV
5.2%):
5.2 (%) x 568 (ml) ÷ 1,000 = 2.95 units
