Degree to Radian Converter

How to Use the Calculator

1. Enter the angle in degrees into the "Degrees" input field.
2. Click the "Calculate" button to convert the angle to radians.

Working Principle

Radians and degrees are both units for measuring angles. A full circle is 360 degrees or 2π radians. To convert degrees to radians, you multiply the angle in degrees by π/180.

Example

If you want to convert 90 degrees to radians:

90 degrees × (π / 180) = π/2 radians ≈ 1.5708 radians
