📐 Sphere Calculator
Calculate sphere volume and surface area
How Sphere Calculation Works
- 1Enter the radius (or diameter or volume) of the sphere.
- 2Volume = (4/3)πr³, Surface Area = 4πr².
- 3All properties are computed and displayed with the formulas.
About Sphere Calculator
Calculate volume, surface area, and diameter of a sphere. Enter the radius and get all measurements with formulas shown.
Frequently Asked Questions
Can I enter the volume to find the radius?
Yes. Enter any one known value and the calculator solves for all other properties.
What units does it use?
It works with any units. Just be consistent — if radius is in cm, volume will be in cm³ and surface area in cm².
