Note: the US Dietary Guidelines suggest up to 2 drinks a day for men and 1 for women, if you drink at all. Standard drinks say nothing about whether it is safe to drive – do not drink and drive.
In the US a standard drink contains 14 g (0.6 fl oz) of pure alcohol – about 12 fl oz of 5% beer, 5 fl oz of 12% wine or 1.5 fl oz of 40% spirits. A UK unit is 10 mL (8 g) of alcohol and an Australian standard drink is 10 g.
Pure alcohol (g) = volume (mL) × ABV ÷ 100 × 0.789, the density of ethanol. Divide by 14 for US standard drinks. UK units = volume (mL) × ABV ÷ 1,000.
A 750 mL bottle of 13% wine has about 77 g of alcohol: 5.5 US standard drinks or 9.75 UK units.
A 16 fl oz can of 7% IPA is about 1.9 US standard drinks.
A UK pint (568 mL) of 4% beer is 2.3 units; at 5% it is 2.8 units.
