## User Guide

This tool will calculate the volume of a sphere from the radius, and will convert different measurement units for radius and volume.

### Formula

The formula used to calculate sphere volume is:

V = (4/3) · π · r^{3}

#### Symbols

- V = Sphere volume
- π = Pi = 3.14159…
- r = Sphere radius

### Radius of Sphere

Enter the radius of a sphere. The radius is the distance between the centre and any point on the surface of a sphere.

### Volume of Sphere

This is the volume contained within a sphere with the specified radius.
