User Guide

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

Formula

The formula used to calculate the circle diameter is:

ø = 2 x √(A / π)

Symbols
  • ø = Circle diameter
  • A = Circle area
  • π = Pi = 3.14159…

Area of Circle

Enter the area contained within a circle.

Diameter of Circle

This is the diameter of a circle that corresponds to the specified area. The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle, or any two points on the circle as long as they are exactly 180 degrees apart.
