Because of the definition of pi, in a circle with a diameter of one there are 2000 π milliradians (≈ 6283.185 mrad) per full turn. In other words, one real milliradian covers just under 1 / 6283 of the circumference of a circle, which is the definition used by telescopic rifle sight manufacturers in reticles for stadiametric ...

Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...

Stadiametric rangefinding often uses the milliradian ("mil" or "mrad") as the unit of angular measurement. Since a radian is defined as the angle formed when the length of a circular arc equals the radius of the circle, a milliradian is the angle formed when the length of a circular arc equals 1/1000 of the radius of the circle.
