Radians to Degrees Converter

Multiply radians by 180/π. For example, π/2 radians = (π/2) × (180/π) = 90°. Key values: π rad = 180°, 2π rad = 360°, 1 rad ≈ 57.2958°.

1 radian ≈ 57.2958 degrees. A radian is the angle subtended at the center of a circle by an arc equal in length to the radius. A full circle is 2π ≈ 6.2832 radians.
