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
- Enter the density in either Specific Gravity or
- Enter the temperature in either C or F.
- Enter the hydrometer calibration in either C or F.
- Press the calculate button.
- The corrected reading will be displayed.
- Specific gravity should be entered as 1.xxx. For
example, a s.g. reading of 1.045 is sometimes referred to
as 45 gravity units. This reading must be entered as 1.045
for correct results.
- Most hydrometers are calibrated to 15C (60F) or 20C
(68F). If you are unsure of the calibration for your
hydrometer, enter a value such as 64F. The resulting error
will be insignificant.
- You can mix temperature scales. For example, you can
enter the calibration in degrees F and the measured
temperature in degrees C. The calculator will automatically
calculate the conversions.
