-1.257 radian
"Radian" is a distance. "Revolution per minute" is a speed. Those two units measure different quantities, and they don't convert into each other. It'll help to know that 1 revolution is (2 pi) radians. So "one revolution per minute" is "2 pi radians per minute", etc.
Degrees = (180/pi)*Radians
1 rotation/1 min * 1 min/60s * (2*Pi radian/1 rotation)
You must multiply that by pi/180, to convert to radians.

Multiply the degree measure by (1/(180 times pi))

No. Centimetres are a measure of linear displacement whereas radians measure angular displacement. Because they measure different things, it is not possible to convert from one to the other.
radian = 180/2pi degrees
Well, a radian is a measure of angle. A meter is a measure of length. You cannot convert a radian to a meter without having more data. If, for example, you ask how long is the arc of a circle whose radius is one meter and whose angle is two radians, the answer is two meters.
The radian measure IS the arc length of the unit circle, by definition - that is how the radian is defined in the first place.
In radian measure, 2pi radians is a full circle. In degrees, 360° is a full circle, so 2pi radians = 360°. If you want to convert: Radians = (2*pi/360)*Degrees = (pi/180)*degrees. And Degrees = (180/pi)*Radians.
