One radian equals approximately 57.2958 degrees. This is calculated as 180 divided by pi.
Multiply the value in radians by 57.2958 (or equivalently, multiply by 180/pi). For example, 2.5 radians × 57.2958 = 143.239 degrees.
Pi radians equals exactly 180 degrees. This is the defining relationship between the two angular measurement systems.
Yes, most programming languages (JavaScript, Python, C++) use radians for trigonometric functions like sin(), cos(), and tan(). You must convert degrees to radians before passing to these functions.
