The toRadians() method converts degrees to radians. toDegrees() converts radians to degrees. Here is a program that demonstrates toRadians() and toDegrees():

// Demonstrate toDegrees() and toRadians().
class Angles {
public static void main(String args[]) {
double theta = 120.0;
System.out.println(theta + " degrees is " +
Math.toRadians(theta) + " radians.");
theta = 1.312;
System.out.println(theta + " radians is " +
Math.toDegrees(theta) + " degrees.");
}
}

The output is shown here.

120.0 degrees is 2.0943951023931953 radians.
1.312 radians is 75.17206272116401 degrees.

Actually, 120º *is* 2.0943951023931953 radians because 180º is pi radians (i.e. roughly 3.1416 radians).

I believe you may be confusing radians and gradians, although even gradians would not be right with what you're saying.

So, don't despair ... Java is not broken, but the world's Mathematicians are crying.
