How much alcohol is there in my beer if I have a refractometer? I compiled two tools from Univers Bière and made my own down here:
There is also this convertor that is rather convenient.
I like charts, when they’re pretty. Occasionally I’ll need to be able to quickly convert from Brix to gravity, typically to compute added sugar to reach a specific gravity (those computations are easier to do using gravity than Brix).
