How to convert 1 US gallon of water to pounds?

To convert a quantity of a substance or material expressed as a volume to mass we simply use the formula:

mass = density × volume

We want to calculate the mass in pounds from a volume in US gallons. We have the density table at the bottom of this web page that shows us the densities values in kg/m³, so we will use the folowing formula (see why below):

mass = d × v × vcfmcf, where mcf is the conversion factor to convert from pound to kilogram (table near the end of this page) and vcf is the conversion factor to convert from US gallon to cubic meters.

So, plugging these values in the formula above, we get:

mass = 1000 × 1 × 0.003785410.453592

mass = 3.785410.453592

mass = 8.3454 pounds (answer)
