Formula and calculation method
Box: V = length × width × height. Cylinder: V = πr²h. Sphere: V = 4πr³/3. Cone: V = πr²h/3.
Use consistent units for all comparable inputs. The displayed result is rounded; arithmetic is performed with the full available numeric precision. Check your source measurements before relying on the result.
How to use volume calculator
- Set Solid by choosing the option that matches your calculation.
- Set Length or radius. The example below uses 3.
- Set Width (box only). The example below uses 4.
- Set Height. The example below uses 5.
- Select Calculate to update the result. Reset restores the illustrated inputs. Copy, print or download your own result if you need a record.

Factors affecting your result
Use consistent units for all comparable inputs. The displayed result is rounded; arithmetic is performed with the full available numeric precision. Check your source measurements before relying on the result.
Changing solid changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.
Frequently asked questions
How does the volume calculator work?
Box: V = length × width × height. Cylinder: V = πr²h. Sphere: V = 4πr³/3. Cone: V = πr²h/3.
What inputs does Volume Calculator need?
Enter solid, length or radius, width (box only), height. Choose values that correspond to the same situation and measurement convention.
How should I interpret the volume calculator result?
Use consistent units for all comparable inputs. The displayed result is rounded; arithmetic is performed with the full available numeric precision. Check your source measurements before relying on the result.
Are my volume calculator inputs uploaded?
No. The calculation runs in this browser. Favorites, recent tool names, theme and formatting preferences may be saved locally, but calculation inputs are not sent to a calculation server or stored by this website. Shared links do not include entered values.
