Understanding Radian to Circle Conversion

What is a Radian?

A radian is the SI unit for measuring angles, defined as the angle made at the center of a circle by an arc whose length equals the radius. One complete circle contains 2π radians (approximately 6.28318 radians).

Converting Radians to Circles

To convert from radians to circles, multiply the angle in radians by 1/(2π) or approximately 0.159155. This conversion factor comes from the fact that one circle equals 2π radians.

Example:

π radians = π × 0.159155 = 0.5 circles (half a circle)
