How to convert 1 US gallon of water to kilograms?

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 kilograms 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 vcf is the conversion factor to convert from US gallon to cubic meters (table near the end of this page) and mcf equals 1 because the mass is already in kiliograms.

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

mass = 1000 × 1 × 0.0037854117841

mass = 1000 × 0.003785411784, or

mass = 3.78541 kilograms (answer)
