The tank capacity calculator is a versatile tool for determining the volume of tanks of various shapes. It can compute the volume for 12 different tank geometries, including horizontal, vertical, oval, and more, making it useful for both industrial and domestic applications.
Choose from standard cylindrical and rectangular tanks, as well as cone-top, cone-bottom, and capsule-shaped tanks. The choice of tank shape depends on its application, whether for storing liquids, processing chemicals, or mixing ingredients.
When measuring tank volumes, it’s important to understand the different units you may encounter. Units include m³, cm³, yd³, US gallons, ft³, and liters. To simplify calculations, here is a conversion table:
| \(1m^{3}\) | 1000 L |
| \(1m^{3}\) | 1,000,000 \(cm^{3}\) |
| \(1m^{3}\) | 1.308 \(yd^{3}\) |
| \(1m^{3}\) | 264.172 US gallons |
| \(1m^{3}\) | 35.3147 \(ft^{3}\) |
The tank capacity calculator shows results in all common units, making it easy to convert between gallons, liters, or cubic meters.
The shape of a tank determines its volume. Simple geometric solids like cylinders, spheres, and cones can be measured accurately using their standard formulas. For more complex tanks, the calculator provides the necessary computations for 12 different tank types.
To calculate the volume of a horizontal cylindrical tank, measure the cylinder’s length and the radius of its circular ends:

Volume formula: V = π × r² × L
Consider a horizontal cylinder with length 12 m and diameter 5 m:
r = d / 2 = 5 / 2 = 2.5 m
V = (22/7) × (2.5)² × 12
V ≈ 267.86 m³
V ≈ 267,860 L
V ≈ 70,756 US gallons
The vertical cylinder tank volume is calculated using height and radius:

Volume formula: V = π × r² × h
Volume = Length × Width × Height

Volume is calculated by finding the cross-sectional area first:
Area = π × r² + 2 × r × a
Volume = Area × L

Volume = (π × r² + 2 × r × a) × H

Volume combines cylindrical section and hemispherical ends:

V = (π × L × W × H) / 4



V = (1/3) π h (r² + rR + R²)

V = (4/3) π r³

Output:
US gallons measure liquid volumes in the United States. 1 m³ = 264.172 US gallons.
1 kg of water ≈ 1 liter at 4°C. Useful for mass-to-volume conversions.
Volume (ft³) = Length × Width × Height in feet.
Volume is the amount of 3D space an object occupies. Formula: Volume = Length × Width × Height
The tank capacity calculator makes it simple to measure volumes of tanks with various shapes. By selecting the correct tank geometry, you can get volumes in liters, gallons, cubic feet, or cubic yards.
