Volume Calculator
Calculate the volume of a cube, box, sphere, cylinder, cone, or pyramid. Choose a shape, enter its dimensions, and get an instant result.
Recommended Settings
Pro Tips
- •Volume is always expressed in cubic units - if your inputs are in centimeters, the result is in cubic centimeters
- •A pyramid or cone's volume is exactly one-third of a prism or cylinder with the same base and height
- •Enter dimensions using any consistent unit - the formulas work the same regardless of whether you're using inches, meters, or feet
- •All results are calculated using standard geometric formulas

Frequently Asked Questions
What formulas does this tool use?
Cube: side³. Box: length × width × height. Sphere: (4/3)πr³. Cylinder: πr²h. Cone: (1/3)πr²h. Square Pyramid: (1/3) × base² × height.
What units does the result use?
The result is in cubic units matching whatever unit you entered for the dimensions. If you enter measurements in centimeters, the volume is in cubic centimeters.
Can I use decimal measurements?
Yes. All dimension fields accept decimal values for precise measurements.
Is my data sent to a server?
No. All calculations happen instantly in your browser using JavaScript. Nothing you enter is transmitted anywhere.
Why can't I enter a negative dimension?
Physical dimensions like length, radius, and height can't be negative, so the calculator only accepts zero or positive values.
