- Enter a positive radius and choose its unit.
- Select Calculate volume to apply V = 4/3πr³.
- Review the exact formula, rounded result, and equivalent cubic units.
The sphere volume formula
A sphere’s volume is V = 4/3πr³, where r is the radius. The radius must be measured from the center of the sphere to its surface, and cubing the radius means the result uses cubic units.
Radius, diameter, and unit handling
If you know the diameter, divide it by two before entering it as the radius. The calculator keeps the selected unit and also converts the result to cubic centimeters, cubic meters, and liters when the unit is recognized.

What is the formula for sphere volume?
The formula is V = 4/3πr³, where r is the sphere radius.
Should I enter radius or diameter?
Enter the radius. If you have a diameter, divide it by two first.
What units can I use?
You can enter millimeters, centimeters, meters, inches, feet, or yards. The result is expressed in the corresponding cubic unit.
Does the calculator use an approximation of pi?
It uses the browser’s Math.PI value and displays a rounded result while keeping the full precision in the calculation.
