I find it utterly bizarre that the size of a "drink" is quoted here in ounces, so here's a conversion (assuming I have selected the right kind of ounce for my conversion):
12 ounces of beer is ~340ml, about a normal water drinking glass, or about 0.60 pints, or about 0.72 of those weird American pints.
5 ounces of wine is ~142ml, which is slightly more than a small wine glass. Most wine glasses are 125ml, although there are also lots that are 250ml.
1.5 ounces of spirits is ~42.5ml, which is somewhere between a single and a double shot.
