About the units
What is a radian?
The SI angle unit — the angle subtended when the arc length equals the radius. A full circle is 2π radians, so 1 rad ≈ 57.2958°. Used throughout mathematics and physics.
What is a degree?
The everyday angle unit — 360 degrees make a full circle, so a right angle is 90° and a straight line 180°. Divided into 60 arcminutes each of 60 arcseconds.
