Degrees

A circle is comprised of 360°, which is called one revolution

Degrees are used primarily to describe the size of an angle.

The real mathematician is the radian, since most computations are done in
radians.

Radians

1 revolution measured in radians is 2π, where π is the constant approximately
3.14.

How can we convert between the two you ask?

Easy, since 360° = 2π radians (1 revolution)

Then, 180° = π radians

So that means that 1° = radians
180
