Corrected specific gravity:

Information

Correct for temperature when measuring specific gravity using a hydrometer.

Formula:

correctedSg = measuredSg * ((1.00130346 - 0.000134722124 * measuredTemp + 0.00000204052596 * Math.pow(measuredTemp, 2) - 0.00000000232820948 * Math.pow(measuredTemp, 3)) / (1.00130346 - 0.000134722124 * calibrationTemp + 0.00000204052596 * Math.pow(calibrationTemp, 2) - 0.00000000232820948 * Math.pow(calibrationTemp, 3)))
