About This Calculator
This volume calculator is a powerful tool for calculating the volume of 14 common 3D geometric shapes. It supports unit conversions (cm, m, in, ft) and handles complex formulas for solids like spheres, frustums, and truncated pyramids.
The calculator automatically converts all length inputs to meters for consistent internal computation, and then displays the result in the preferred output unit (e.g. cm³, m³, ft³).
How It Works
Select a shape from the dropdown menu, enter the required dimensions, and choose appropriate units. The tool performs conversion to meters, applies the corresponding volume formula, and returns the result in your preferred volume unit.
- Choose the shape (e.g. Cube, Sphere, Cylinder).
- Input dimensions like radius, height, length, etc.
- Click "Calculate" to get the volume.
Frequently Asked Questions
What units can I use in this calculator?
You can input lengths in centimeters (cm), meters (m), inches (in), or feet (ft). The calculator converts all inputs to meters internally.
How is the output unit determined?
The output unit (e.g. m³, cm³, ft³) is automatically based on the unit of the first primary dimension field for each shape.
Can I use this calculator for irregular or curved objects?
This calculator is designed for ideal geometric shapes. For irregular objects, volume estimation methods such as displacement or scanning are recommended.
What happens if I enter a smaller top than bottom in frustum shapes?
The tool validates that the top dimensions do not exceed the base, and that all values are positive.
