Calculate volume or convert units
Volume of common shapes
The volume calculator handles rectangular boxes, cubes and cylinders. It can also convert between cubic meters, cubic centimeters and liters.
Formulas
- Box volume = length x width x height.
- Cube volume = side cubed.
- Cylinder volume = pi x radius squared x height.
Conversions
The calculator shows converted values for common volume units. Check your source measurements carefully, because the result depends directly on the dimensions entered.
How to choose a shape
Use box or cube when the sides are straight and rectangular. Use cylinder when the object has a circular base, such as a pipe, tank or round container.
Practical limits
Real containers may have rounded corners, wall thickness or unused space. Treat the result as a geometric estimate unless the object exactly matches the selected shape.
