n radians = n/tau or n/(2*pi) of a whole turn.
equivalently, 360/tau or 180/pi degrees.
n degrees = n*tau/360 or n*pi/180 radians.
They are different measures of angular displacement.n degrees = n*tau/360 (or n*pi/180) radians.
The radian is 0.523598776
1 degree = pi*radian/180 So therefore 15 times pi*radian/180 = pi*radian/12

Radian - Morituri - was created in 1986.
A radian is an arc of the circumference of a circle and it is about 57.3 degrees.
One radian is about 57.3 degrees
A radian is 180/pi degrees, or about 57 degrees
-1.257 radian
radian = 180/2pi degrees
A mile is an obsolete unit of distance and the radian is a unit for angles !
