Enter the diameter or circumference in the tool to find the relative measurements of circle
Use the circumference to diameter calculator for precise and accurate conversion of diameter from circumference and vice versa. Get complete steps involved to get the diameter from the circumference with utmost accuracy.
A circle is round and symmetrical and each point is equidistant from its center. A circle has several properties which include the circumference and diameter.
It is the perimeter of a circle and the measure of the boundary or the area of circular edges. Circumference is the total length of the outer edges of the circle.
It is a straight line that passes through the center of the circle and extends from one edge. The diameter connects two points of the circumference with each other and it represents the width of the circular object. The circumference to diameter calculator convert circumference to diameter and vice versa.
The diameter of a circle formula from circumference is: d = C/π The circumference of the circle is:
C = πd
Where:
d = diameter
C = Circumference
π = ratio of a circle's circumference to its diameter
The diameter to circumference calculator provides an easy procedure to calculate diameter from circumference.
Let’s suppose the diameter of a circle is 10 cm, then what is its circumference?
Given:
D = 10 cm
C =?
Solution:
C = πd
C = (3.14)(10)
C = 31.416 cm

Let’s suppose the circumference of the circle is 60, then calculate diameter from circumference.
Given:
C = 60 cm
d = ?
Sol:
d = C/π
d = 60/π
d = 19.099 cm

Our calculator does conversion from diameter to circumference in no time if provided with the following inputs:
Input:
Output:
Circumference = 2×π×r
C = 2×3.14×24
C = 150.72 inches
If the area of a circle is given, then the formula to calculate the perimeter or circumference of a circle is given by:
C = 2√(πA) units.
As we know, the Circumference of a circle if its diameter is given = π × d units. Substituting d = 7 cm in the formula, we get C = π × 7 = 7π units.
