One 500 ml beer is 1.0 drink in Austria and 2.5 drinks in the UK.
Countries define a "standard drink" as anything from 8 to 20 grams of pure alcohol. Add your own drinks and see how many standard drinks the same glass counts as in each country.
Guess first
A 500 ml beer at 5% ABV counts as how many standard drinks there?
1.5
Your tab
PURE ALCOHOL 0 g
IN YOUR COUNTRY 0
Grams = volume x ABV x 0.78945 g/mL, the density of ethanol at 20 C. Preset pours: 500 ml of 5% beer (the comparison pour on Wikipedia), 5 imperial oz of 12% wine and 1.5 imperial oz of 40% spirit (Canadian reference sizes, rounded to ml). Edit any number.

Where the table lists a range (Luxembourg 10 to 12 g, Mexico 10 to 13 g) this page uses the midpoint. Canada lists 13.6, 13.45 or 13.5 g; 13.6 is used. Japan has two definitions and both are shown. Real pours and real beverages vary; this is a unit converter, not advice about how much is safe.
