About these units

Mil: The mil is a military angular unit used in ballistics, optics, and range estimation.In the NATO system, a full circle is divided into 6400 mils.

Radian: The radian (rad) is the SI derived unit of plane angle. It is defined as the angle subtended at the center of a circle by an arc equal in length to the radius.Although mathematically dimensionless, th...
