So I want to learn to use my refractometer for FG not just during brew day. OG 1.050 (12.5brix) FG 1.012 (FG 3brix) =4.99% All good. BF refrac calculator tells me it’s 8% 1.050 3 brix 1.0 correction factor 8% what am I doing wrong?
Try this calculator. It has an explanation and a converter. https://www.brewersfriend.com/brix-converter/
The calculator on this site works just fine, it's just annoying that it won't take measured gravity in specific gravity.
