BrewUnited's Gravity/Temperature Correction Tool


It never hurts to have
another hydrometer on hand!
Hydrometers are used to measure the specific gravity of your beer. They are calibrated to be accurate at a specific temperature (60 degrees F and 68 degrees F are popular calibration temperatures), but they lose accuracy as the beer temperature deviates from this calibration temperature. This is due to the fact that solutions are less dense at higher temperatures.

Fortunately, we can calculate the difference easily enough. If you'd prefer to not do the calculations by hand, you can always use this gravity/temperature adjustment tool. Many similar tools assume a set calibration temperature (often, 59 degrees F, which was once the most popular such calibration), but this tool allows you to specify any calibration temperature.

If you enjoy the gravity/temperature adjustment tool or find it useful (or entertaining), please consider sharing it via one of the buttons below. Thanks!
