Lastly, convert cubic feet or cubic meters to gallons. Then multiply this result by 4/3 to account for the shape of a sphere. Square this value and multiply it by pi (about 3.14159). Volume (gallons) = π × Radius² (ft) × Height (ft) × 7.48051948Ĭalculating capacity for a spherical tank requires measuring its diameter and obtaining its radius by dividing the diameter in half. Finally, convert cubic units into gallons using conversion factors similar to rectangular tanks. Multiply this value by pi (approximately 3.14159) and then by the height of the tank to find its volume in cubic feet or cubic meters. Divide the diameter by 2 to find the radius and square it. To calculate the gallons in a cylindrical tank, measure the diameter and height of the tank in feet or meters. Volume (gallons) = Length (ft) × Width (ft) × Height (ft) × 7.48051948 To convert cubic feet to gallons, multiply the volume by 7.48051948 (1 cubic foot equals 7.48051948 gallons), and for cubic meters to gallons, multiply by 264.172053 (1 cubic meter equals 264.172053 gallons). Then multiply these values together to obtain the volume in cubic feet or cubic meters.
In this article, we’ll guide you through the process of calculating gallons in a tank using various methods.įor rectangular tanks, simply measure the length, width, and height of the tank in feet or meters. It can help you understand your tank’s limitations and ensure the optimal use of its storage capacity.
Calculating the gallons in a tank is essential for a variety of purposes, such as determining the capacity of fish tanks, fuel storage containers, or water storage systems.
