How to convert Radians to Degrees?
Radians and degrees measure angles. The relationship is:
- π radians = 180°
- 1 radian = 180/π degrees
To convert Radians to Degrees, multiply radians by 180/π.
Formula: Degrees = Radians × (180 ÷ π)
Step-by-Step Calculation
- Take the number of Radians you want to convert (e.g., π/2).
- Multiply that value by 180/π.
- The result is the value in Degrees. (Example: (π/2) × 180/π = 90°).
