Moromi: brewing calculators that show their work

Field notes

The suite covers both familiar brewing math and process-specific corrections, including refractometer readings affected by alcohol and hydrometer readings taken at the wrong temperature. Its IBU calculator supports Tinseth and Rager methods, while the gravity tool converts among specific gravity, Plato, Brix, and gravity points. The page states that calculations stay in the browser and that each card exposes its formula; it also presents metric and US unit modes.
