Converting Radians to Degrees

To convert a value in radians to degrees, multiply it by 180/π:

using System;

public static double ConvertRadiansToDegrees(double radians)
{
    double degrees = (180 / Math.PI) * radians;
    return (degrees);
}

public static double ConvertDegreesToRadians (double degrees)
{
    double radians = (Math.PI / 180) * degrees;
    return (radians);
}
