Alcohol (ethanol-water) gauging, blending, dilution and concentration conversions. Data covers temperatures from -20C to 100C (-4F to 212F) and strengths from 0% to 100% (200 Proof). Work in mass or volume terms. Wide selection of units built in for temperature, density, mass and volume. Accuracy in accordance with OIML data. Blending, dilution and fortification calculations in mass or volume (or mixed) terms. Automatically compensate for temperature. Takes shrinkage (contraction) into account for full accuracy in determining strength and volume. Print blending reports. Hydrometer correction for temperature in gauging. Use a density, ABV or Proof hydrometer and convert apparent strength to true strength for all 3 types plus mass %. Works for any calibration temperature. Transfer true strength to calculator to determine true quantity. Volume temperature correction calculator for inventory management. Convert volumes from one temperature to another and determine absolute alcohol (Proof gallons) content. Convert between mass and volume quantities. Convert between density and strength for any two of Density, Mass %, Volume % (ABV), Proof or Molar % taking temperature into account where necessary. Freezing point (melting point) calculator to determine freezing temperature from strength, or vice versa.
