How do I convert gallons to pounds? 

If you need to convert gallons to pounds, it is best to use a gallons to pounds calculator like the one here, as you need to consider the density of the liquid.  To convert between a unit of volume and a unit of mass, we need to use the equation density = mass / volume   The density of water at 39.2 °F (4.0 °C) is 1 g/ml.  We use this density to convert gallons to pounds or convert pounds to gallons (lbs to gallons). However, since this density is in the metric system, and gallons and pounds are in the imperial system, we need to make some additional conversions.  Thankfully, this calculator does that for you, so you don’t need to worry about it!  We also have included the densities of several other liquids, including oil, gasoline, and milk.
