About this calculator

This volume calculator covers the most common 3D shapes used in school work and everyday tasks, with the formula shown next to each input set. Units are for labelling only, so if you measure in centimetres you will see the output as cm³. If you need conversions, use a converter first, then paste the converted numbers here.

The tool works entirely in your browser. Your selections are reflected in the URL for quick sharing, and the CSV export captures your inputs and results for notes or documentation.
