The circumference of a circle is a fundamental measurement in geometry, representing the distance around the circle. Whether you’re a student, engineer, or DIY enthusiast, calculating circumference is essential for various applications. Our Circumference Calculator simplifies this process by providing quick and accurate results based on either the radius or diameter of the circle.
Select Calculation Method – Choose whether you want to calculate using the radius or diameter of the circle.
Enter the Value – Input the numerical value of the radius or diameter.
Select Unit – Choose your preferred unit of measurement (centimeters, meters, inches, or feet).
Calculate – Click the “Calculate Circumference” button to get instant results.
The calculator will display the circumference along with the corresponding radius and diameter, ensuring you have all the necessary measurements.
The circumference (C) of a circle can be calculated using two primary formulas:
Using Radius (r):
Using Diameter (d):
Where π (pi) is approximately 3.1416.
