What is the Sphere Volume Calculator?
Calculate the volume and surface area of a sphere. These geometry calculators work out area, perimeter, volume and surface area for common shapes. Units are flexible — enter every length in the same unit and the answer comes back in that unit (squared or cubed).
How to use the Sphere Volume Calculator
- Enter your radius.
- Results update automatically as you type; you can also press Calculate.
- Read the output: volume, surface area, diameter.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Worked example
With radius = 6, the Sphere Volume Calculator returns volume: 904.778684234; surface area: 452.389342117; diameter: 12.
Tips for better results
- Keep all measurements in one unit before calculating.
- Area units are squared (m², ft²) and volume units are cubed (m³, ft³).
- Use our area and volume converters to switch units afterwards.
