glass hydrometer temp/conversion chart

[zoebeaglezoe]

was wondering if anyone knows or has a conversion chart to use for glass hydrometers mine lists at 75deg. f.

thanks

It's normally one point of correction per 3 degrees. If temperature is 78, and your gravity reading is 1.025, then the corrected gravity is 1.026. That should work for the lower range saltwater gravity, I know that's the thumbrule we used for battery specific gravity. HTH
