Enter the cross-sectional area and height of the liquid into the calculator to determine the volume in gallons. This calculator can also evaluate any of the variables given the others are known.

Inches To Gallons Formula

The following formula is used to calculate the volume of liquid in gallons from a measurement in inches. 

V = A * h * CF

Variables:

  • V is the volume of the liquid in gallons (gal)
  • A is the cross-sectional area of the container (in^2)
  • h is the height or depth of the liquid (in)
  • CF is the conversion factor from cubic inches to gallons (gal/in^3), approximately 0.004329

To calculate the volume of the liquid in gallons, multiply the cross-sectional area of the container by the height or depth of the liquid. Then multiply the result by the conversion factor from cubic inches to gallons.

What is Inches To Gallons?

Inches to Gallons is a conversion method typically used to calculate the volume of liquid in a cylindrical or rectangular container. It involves converting the height or depth measurement (in inches) of the liquid into its volume (in gallons). This is often used in scenarios such as measuring the amount of fuel in a tank or water in a pool. The exact conversion factor can vary depending on the shape and dimensions of the container.

How to Calculate Inches To Gallons?

The following steps outline how to calculate the Inches To Gallons using the formula V = A * h * CF.

  1. First, determine the cross-sectional area of the container (A) in square inches (in^2).
  2. Next, determine the height or depth of the liquid (h) in inches (in).
  3. Next, gather the conversion factor (CF) from cubic inches to gallons (gal/in^3), which is approximately 0.004329.
  4. Finally, calculate the volume of the liquid (V) in gallons (gal) using the formula V = A * h * CF.
  5. After inserting the values for A, h, and CF, calculate the result to obtain the volume of the liquid in gallons.

Example Problem:

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

Cross-sectional area of the container (A) = 10 in^2

Height or depth of the liquid (h) = 5 in

Conversion factor (CF) = 0.004329 gal/in^3
