Calculation Formula

Volume (Gallons) = Length (in) × Width (in) × Height (in) × 0.00378541

Where:
Length (in) = Length of the tank in inches
Width (in) = Width of the tank in inches
Height (in) = Height of the tank in inches
0.00378541 = Conversion factor from cubic inches to gallons

Learn how to use the Inches to Gallons Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the length of your tank in inches.
  2. Enter the width of your tank in inches.
  3. Enter the height of your tank in inches.
  4. Click the "Calculate" button to convert the volume from cubic inches to gallons.
  5. The result will be displayed in gallons.

Working Principle

The calculator works by first calculating the volume of the tank in cubic inches (Length × Width × Height) and then converting that volume to gallons using the conversion factor of 0.00378541 (which is the number of cubic inches in one gallon).

Example

If you have a tank that is 12 inches long, 10 inches wide, and 6 inches high, the volume would be:

12 in × 10 in × 6 in = 720 cubic inches

720 cubic inches × 0.00378541 = 2.727348 gallons
