What is Turn?

The turn represents one complete rotation, equal to 360 degrees, 2 pi radians, or 400 gradians. It is the most intuitive angular unit in everyday language: a "half turn" is 180 degrees, and a "quarter turn" is 90 degrees. In sports, figure skating jumps are described in turns (a triple axel is 3.5 turns), and skateboard tricks use 360 for one full rotation. In engineering, rotational speed in RPM is based on the turn.

What is Milliradian?

The milliradian is one-thousandth of a radian, approximately 0.0573 degrees. It is widely used in military and shooting applications, where NATO standard scopes use milliradians for angular measurement. One mrad subtends approximately one meter at a distance of 1,000 meters, making range estimation intuitive. Laser beam divergence and optical aberrations are also often specified in milliradians.
