milliradian
Tiny angle measure
A milliradian is one-thousandth of a radian—a unit of angular measurement used primarily in ballistics, optics, and military applications.
At 100 meters, one milliradian subtends approximately 10 centimeters, making it practical for calculating bullet drop and windage adjustments: The scope has milliradian turrets.
Often shortened to mil or mrad.
