Ok, so I got a screaming deal on a ATC refractometer. Only catch is it only measures in Brix. Fine, I get it, brix x 4 = SG.
Or does it?
Apparently in attenuating there is some relative computation that occurs that I just don't understand.
For example:
If I put in 15 brix by itself that is 1.060. If I put in 5 brix by itself that is 1.020. But if I put in 15 brix as my OG and 5 brix as my FG I then find that I have a gravity of <1. In other words as an OG 5 brix = 1.020 but as an FG in relation to an OG of 15brix 5 brix is then .995.
I'm so cornfused by this. Can someone explain or point me to a document that explains????
Thanks!
