Thanks. I'm fine with metrics, so this translates into something concrete. So what we call a fifth (750ml) is 75 units, and 40 units of wine is like drinking 1/2 of a fifth of the hard stuff. My guess is that this will be helpful for a lot of us here.
Also, I don't know why I didn't google this myself. I usually do, but sometimes I space out assuming only a human would know the answer. It's a generational thing, I guess. lol
