Trying to convert 3 gallons of a chemical into Lbs. the specific gravity is 1.31. Any help greatly appreciated.

The specific gravity is its density as compared to pure water at standard temperature and pressure.

A specific gravity of 1.31 is 1.31 kilograms/liter

1 kilogram = 2.20462262184878 pound
1 liter = 0.264172051241558 gallon [US, liquid]

1.31 * (kilogram to pound)/(liter to gallon) = pound/gallon

So a specific gravity of 1.31 means a density of about 10.93 pounds per gallon

I love this site because Mr. Fogt always gives explanations of derivations.  VERY helpful in understanding the conversion methods used!!!   :)

An easier way to convert from specific gravity to lb/gal is to remember that the SpG of water = 1.  Water is (roughly) 8.34 lb/gal.  So, just multiply the SgG that you're given (1.31 in this case) times 8.34, and you get 10.925 lb/gal, or 10.93...
