# Circumference of a Cylinder Calculator

Welcome to the Omni **circumference of a cylinder calculator,** a convenient and easy-to-use tool to help you determine what is the circumference of a cylinder. Are you wondering **how to find the circumference of a cylinder?** Or maybe you're just interested in **what is the circumference of a cylinder** in general?

Regardless, **grab your ruler** or a measuring tape, **and the circumference of a cylinder calculator will do the calculations for you!**

## How do I find the circumference of a cylinder? Circumference of a cylinder formula

Let's start from the beginning - **what is circumference?** The circumference is a linear distance around the edge of a circle or ellipse. Since a cylinder's cross-section is a circle, you can **calculate the circumference of a cylinder** using the following formula:

`cylinder_circumference = 2 * π * cylinder_radius`

or

`cylinder_circumference = π * cylinder_diameter`

Let's put the formula for the circumference of a cylinder in perspective. Suppose the radius of a cylinder is 5 cm. To calculate the circumference of a cylinder, you have to multiply five by two and by pi, which equals approximately 31.41 cm.
