Hi Simon, I'm a bit confused about the Standard Drink (US) and UK Unit. The US std. drink contains 14 g. of alcohol, while the UK Unit contains 8 g. Then if 30 mL @ 40% = 14 g of pure alcohol and is one US Drink, then the same volume and concentration in UK Units would be 14/8 g of pure alcohol or 1.75 UK Units, rather than 1.2 units as indicated. Or is my math(s) erroneous?

Thanks for pointing out, Paul. The wine calculation is correct, but 30ml (1oz) of 40% spirit = 0.7 standard drink (not 1 standard drink as previously). Now corrected.
