I want to measure salt brines. I can measure specific gravity and degrees Fahrenheit. I need a formula that I can insert the two measured values into and get the degree of saturation of my brine. I can't find a formula. I'm not sure a formula exists, but I can't understand why not. There are charts to adjust SG for temperature, and Hydrometers scaled with degree of saturation, called by various names like Brinometer, salometer, salinometer and such, but I don't have one of those. My hydrometer just measures specific gravity and is calibrated at 68 degrees Fahrenheit. Can you help me? Am I even posting in the right place?
