# What's the Difference Between Circle and Circumference?

*Circle* and *circumference* are two geometrical terms that often get confused and create doubts when you have to use them. Although you might think they are synonyms, they are not. Don't worry: here at oneHOWTO, we'll show you **what is the difference between circle and circumference**.

According to Merriam-Webster's Dictionary, a **circle** is ‘a perfectly round shape: a line that is curved so that its ends meet and every point on the line is the same distance from the center’.

A **circumference**, on the other hand, is ‘the length of a line that goes around something or that makes a circle or other round shape’.
