Welcome to the Omni cylinder volume gallons calculator, a simple tool that helps you calculate the volume of a cylinder in gallons with input values such as radius, height, and diameter. Don't have necessary parameters? Don't worry, you only need a ruler or a measuring tape! The cylinder volume gallons calculator also lets you convert your input values into different imperial and metric units of measurement, so you don't have to waste your time on conversions. Wait no further; come along to learn how to calculate volume in gallons of a cylinder!

How do I calculate volume of a cylinder in gallons?

The cylinder volume gallons calculator will do all calculations and conversions for you! But if you want to calculate the volume of a cylinder by hand, 😉 you need to utilize the following formula:

V = π * r² * h

Where:

  • V is cylinder volume;
  • r is cylinder radius; and
  • h is cylinder height.

However, since you are looking for cylinder volume in gallons, you will have to take an extra step and convert your unit of measurement. For instance, if the volume of a cylinder is in cubic inches, and you're interested in the volume of a cylinder in gallons, you need to

  1. Take the number (the volume of a cylinder in cubic inches);
  2. Multiply this number by 0.0043 for converting into US gallons or by 0.0036 for converting into UK gallons; and
  3. Ta-da! You calculated the volume of a cylinder expressed in US gallons or UK gallons.

Now that you know how to find the volume of a cylinder in gallons, don't forget to check other cylinder volume-related calculators:
