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
- 1Take the number of Radians you want to convert (e.g., π/2).
- 2Multiply that value by 180/π.
- 3The result is the value in Degrees. (Example: (π/2) × 180/π = 90°).
How to use this converter?
Enter radians and instantly get degrees—useful for geometry, navigation, and when you need degree-based angles.
Tip: Keep π for exact answers
In math, radian values often include π. Converting using 180/π preserves the exact relationship.
