There is no logic for degrees. The degrees of a circle were arbitrarily chosen to be 360, probably because of the magic number 12 (used also in seconds, hours, months, dozen, etc.)
The logic of radians is that the circumference of a circle is 2 pi r, therefor the radians of a circle is 2 pi, making calculations easy.

pi [radians] = 180 [degrees] 1 [degree] = pi/180 [radians] = 0.0174533 [radians] therefore, 2115 [degrees] = 2115 [degrees] * 0.0174533 [radians/degree] = 36.9 [radians]
5 radians = 286 degrees.
285.3° To convert from radians to degrees, multiply by 180° and divide by pi (about 3.14159).
Degrees x 0.01745 = radians
To convert degrees to radians, you need to multiply the degree measure by 2pi/360Multiply 70 by 2pi/360 and you get approximately 1.22173047.
