Calculate Radians in Degrees

Converting between radians and degrees is essential in physics, engineering, and mathematics. This guide explains the conversion process, provides practical examples, and offers an easy-to-use calculator.

Conversion Formula

The relationship between radians and degrees is defined by the following formulas:

Degrees = Radians × (180/π) Radians = Degrees × (π/180)

Where π (pi) is approximately 3.141592653589793. These formulas allow for precise conversion between the two units.

Note: 1 radian is approximately 57.2958 degrees, and 1 degree is approximately 0.0174533 radians.
