One degee = (pi/180)*radian
Integers do not convert directly into radians. Only angular values may, such as degrees or grads. ex: 1x180 degrees = pi radians. 2x180 degrees = 2pi radians. Thusly an angle of 1 degree would be equal to pi/180 x 1 degree.
One revolution = tau radians (or 2*pi radians).
20 times pi There are 2 pi radians in one revolution.

A full circle is either 360 degrees, or 2 x pi radians, so the exact conversion factor is: 1 radian = 180/pi degrees
To convert from degrees to radians, you need to multiply by pi/180. Since one arc-second is equal to 1/3600 of a degree, the conversion factor in this case is pi/180/3600.

One way to remember it is: a full circle is 2pi radians, or 360°, so 2pi radians = 360°, and then you multiply degrees by (2pi/360 radians per degree) = pi/180 radians per degree.
By definition, the number of radians in one complete revolution is given by the ratio of the circumference of a circle to its radius. The circumference of a circle of radius r is of length 2πr. There are thus 2πr/r = 2π radians in one revolution. So, 2π radians = 360° Then 1 radian = 360/2π = 57.296° or 57° 17'
Equal to the length of the radius.
One revolution = tau radians (or 2*pi radians).
One degree of angle is equal to 3,600 seconds of angle.
