Hydrometer Temperature Adjustment Calculator
RAPT Portal | Hydrometer Temperature Adjustment Calculator
The Hydrometer Temperature Adjustment Calculator allows you to adjust hydrometer readings based on the temperature of the sample.
Liquids expand and contract at different temperatures, meaning the liquid can become more or less dense. Hydrometer readings are based on the gravity of the liquid which is directly affected by the density of the liquid, and thus can be incorrect depending on the temperature the hydrometer was calibrated at, and the temperature at which the measurement was taken.
A simple formula is used to allow for compensation at different temperatures.
To make a measurement adjustment
Select your measurement unit (standard gravity, brix).
Enter the hydrometer reading.
Enter the measurement temperature.
Enter the original calibration temperature.
Optionally provide an offset if you have performed a custom calibration.
The adjusted value will be calculated.
