Enter the total weight of the object or substance (lbs) and the total volume (gallons) into the Weight Per Gallon Calculator. The calculator will evaluate the Weight Per Gallon.

## Weight Per Gallon Formula

The following two example problems outline the steps and information needed to calculate the Weight Per Gallon.

WPG = W / G

Variables:

• WPG is the Weight Per Gallon (lbs/gallon)
• W is the total weight of the object or substance (lbs)
• G is the total volume (gallons)

## How to Calculate Weight Per Gallon?

The following steps outline how to calculate the Weight Per Gallon.

1. First, determine the total weight of the object or substance (lbs).
2. Next, determine the total volume (gallons).
3. Next, gather the formula from above = WPG = W / G.
4. Finally, calculate the Weight Per Gallon.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

total weight of the object or substance (lbs) = 100

total volume (gallons) = 50

WPG = W / G = ?
