About these units

The radian (rad) is an SI base or derived unit of angle.

The milliradian (mrad) is a metric unit of angle, equal to 0.001 radians.

Going the other way, 1 milliradian = 0.001 radians. Trigonometry and CAD want radians, surveyors want gradians, navigation wants degrees and minutes. Convert plane angles between every common representation.
