Water Tank Calculator
If you’re planning to install or manage a water storage system, knowing the exact capacity of your tank is essential. The Water Tank Calculator is a powerful and easy-to-use tool that helps you calculate tank volume, water capacity, and total water weight based on shape and dimensions.
Whether you're working with residential storage, agricultural systems, or industrial tanks, this calculator simplifies complex measurements using basic principles of Volume.
What is a Water Tank Calculator?
A Water Tank Calculator is an online tool that determines:
- Tank volume (cubic feet)
- Water capacity (gallons and liters)
- Total water weight (in pounds)
It supports multiple tank shapes, making it versatile for various real-world applications.
Supported Tank Shapes
This calculator allows you to compute capacity for three common tank types:
1. Rectangular Tank
Used in storage containers, aquariums, and underground tanks.
2. Cylindrical Tank
Common in vertical water tanks and industrial storage systems.
3. Spherical Tank
Used in specialized storage systems and certain industrial applications.
Formulas Used in the Calculator
The tool automatically applies the correct formula based on the selected shape:
Rectangular Tank:
- Volume = Length × Width × Height
Cylindrical Tank:
- Volume = π × Radius² × Height
Spherical Tank:
- Volume = (4/3) × π × Radius³
Conversions:
- 1 cubic foot = 7.48052 gallons
- 1 gallon = 3.78541 liters
- 1 gallon of water ≈ 8.34 lbs

Example Calculations
Example 1: Rectangular Tank
- Length: 10 ft
- Width: 5 ft
- Height: 4 ft
Volume = 10 × 5 × 4 = 200 ft³
- Gallons: ~1,496
- Liters: ~5,663
- Weight: ~12,476 lbs
Example 2: Cylindrical Tank
- Diameter: 6 ft
- Height: 10 ft
Volume ≈ 282.74 ft³
- Gallons: ~2,115
- Liters: ~8,005
- Weight: ~17,648 lbs
Example 3: Spherical Tank
- Radius: 3 ft
Volume ≈ 113.10 ft³
- Gallons: ~846
- Liters: ~3,203
- Weight: ~7,060 lbs
