Hydrometer Temperature Adjustment Calculator

This calculator determines the actual specific gravity, after correcting for the sample wort temperature and the hydrometer's calibration temperature.

Be sure to also check out our ABV Calculator, and Brix Converter.

Temperature Units:	US - °F Metric - °C
Hydrometer Units:	Specific Gravity (1.xxx) Brix
Hydrometer Reading:	(1.xxx)
Temperature:	(F)
Calibration:	(F)

Update - October 2012
A browser cookie will now save your hydrometer calibration between visits (but if you clear your cache it disappears).

Update - August 2012
This calculator now supports different hydrometer calibrations. Look on your hydrometer (or its instructions) and it should tell you. Old hydrometers are calibrated to (59° F / 15° C) and newer ones are typically (68° F / 20° C).

The temperature range has been increased to 32-159 °F, 0-71 °C.

Please be careful when handling hot wort! We recommend letting the sample cool to below 100F / 38C before handling. Cracked glassware is a bummer...

NEXT: To calculate your batch's bitterness in the home brewing standard international bittering units (IBUs), see our IBU calculator.
