How to use the volume calculator

  1. Choose the shape you want to calculate the volume of, using the buttons above the calculator.
  2. Enter the measurements — the calculator works out the volume automatically as you type.
  3. See the volume both in cubic units and in liters.

How the volume is calculated

Each shape has its own volume formula:

Sphere: V = (4∕3) × π × r³
Cylinder: V = π × r² × h
Cube: V = s³
Cone: V = (1∕3) × π × r² × h

Sphere and cone include π because they're built on a circular cross-section — π ties the radius to the area of that cross-section, just like with circle area.

Frequently asked questions

Why do sphere and cone formulas include π?

Because both shapes are based on a circular form (the sphere's cross-section and the cone's base), and π is the ratio between a circle's circumference and diameter. It therefore shows up wherever circles and spheres are calculated.

How do I convert from cubic meters to liters?

1 cubic meter (m³) equals exactly 1000 liters. The calculator automatically converts the volume to liters by multiplying by 1000.

Can I use this to calculate how much water a pool or tank holds?

Yes, as long as the pool or tank has one of the four shapes (for example cylindrical). For rectangular pools, see our dedicated pool volume calculator.
