Convert gallons to pounds

Answer 1

You've got to know the weight of the liquid for this to be an accurate conversion. If you just use the weight of water, that's 8.34 pounds/gallon.

So if you have a 5 gallon (g) water jug you're filling up, that will weight 5 x 8.34 pounds or 41.7 pounds.

g x 8.34 = pounds

What if you're wanting the weight of sulfuric acid which has a specific gravity (sg) of 1.84 or 1.84 times that of water, then just multiply your pounds times the specific gravity.

g x 8.34 x sg = pounds

Answer 2

One US gallon of gasoline weighs about 6.3 pounds. So, 500 gallons = 500 x 6.3 = 3,150 pounds.

Answer 3

55 gal to 7040 lbs
