How to Calculate Gallons in a Tank: Simple Formulas for Rectangular & Cylindrical Tanks
Learn how to accurately calculate gallons in rectangular and cylindrical tanks using easy-to-follow formulas and measurements.

To calculate gallons in a tank, firstly measure the tank's dimensions in feet: length (L), width (W), and height (H). For a rectangular tank, the formula is Gallons = L x W x H x 7.48, where 7.48 is the number of gallons in a cubic foot. For cylindrical tanks, use Gallons = π x radius^2 x height x 7.48. Always ensure accuracy by using uniform measurements, and double-check your calculations to avoid errors.
FAQs & Answers
- What is the formula to calculate gallons in a rectangular tank? To calculate gallons in a rectangular tank, multiply length by width by height (all in feet), then multiply by 7.48, the number of gallons per cubic foot: Gallons = L x W x H x 7.48.
- How do you calculate gallons in a cylindrical tank? Use the formula Gallons = π x radius squared x height x 7.48, where radius and height are in feet, and 7.48 converts cubic feet to gallons.
- Why is 7.48 used in tank gallon calculations? Because one cubic foot equals approximately 7.48 gallons, this constant converts volume measured in cubic feet to gallons.
- How can I ensure accuracy when calculating tank gallons? Use consistent units (feet) for all measurements, double-check your calculations, and measure dimensions precisely to avoid errors.
