About the Gallon to Pound Converter
The gallon to pound converter estimates how much a volume of liquid weighs. It multiplies US gallons by the density of the liquid you choose, because a gallon of honey weighs almost twice as much as a gallon of gasoline. Densities are typical values at room temperature and vary slightly with temperature and composition.

How it works
Formula
Pounds = US Gallons × Density (lb/gal)
