## User Guide

This tool will calculate the diameter of a sphere from the surface area, and will convert different measurement units for surface area and diameter.

#### Formula

The formula used to calculate the sphere diameter is:

ø = √(A / π)

###### Symbols

- ø = Sphere diameter
- A = Sphere surface area
- π = Pi = 3.14159…

#### Surface Area of Sphere

Enter the surface area of a sphere. The sphere surface area represents the total area of the outer surface of the sphere if it was to be laid out flat as a two-dimensional shape, e.g. a true scale map of the world is a 2D scaled representation of the surface area of the world.

#### Diameter of Sphere

This is the diameter of the sphere which corresponds to the volume specified. The diameter of a sphere is the length of a straight line drawn between two points on the surface of the sphere, where the line also passes through the centre of the sphere.
