Hydrometers are calibrated for a particular temperature (usually 60F or 68F). Readings will be inaccurate if taken at a temperature that is different than the calibrated temperature. This calculator will determine the corrected reading based on temperature. It supports readings in either specific gravity or brix and will work for hydrometers of any calibration.


  1. Enter the density in either Specific Gravity or Brix.
  2. Enter the temperature in either C or F.
  3. Enter the hydrometer calibration in either C or F.
  4. Press the calculate button.
  5. The corrected reading will be displayed.
