WebThe refraction means your line of sight will be lower than horizontal, but not by as much as the curvature so it doesn't fully cancel out. That leaves the level surface h' below your line … WebRefractometer Calculator. Converts refractometer readings taken of wort (Brix WRI) to their actual value in Brix / Plato and Specific Gravity. Supports alcohol correction of refractometer readings when calculating FG (which requires OG). To help clear up confusion with terminology, at Brewer's Friend we have decided to call a Brix measurement ...
