That's what I do already, it takes 2 seconds. An option to make it automatic would be nice but hardly necessary.

Yes, I mean KG / L as PPL would be nuts :) I appreciate it's not that common but given I'm a metric brewer and not even in the US using US gallons for measuring anything is pretty foreign to me (pardon the pun). Anyway, it's obviously not a major issue as the maths can be done I just thought it...

Is there any way to do this? I have everything set to metric so it's a bit weird to have the contrinutions shown as PPG. Ihe reason I noticed this is that I wanted to double check my pre-boil OG because I just brewed a recipe where I was 5 points under the predicted pre-boil gravity...
