About these units

Degree: The degree (°) is a non-SI unit of plane angle defined as 1/360 of a full rotation.It is accepted for use with the SI due to its long-standing practical importance in navigation, surveying, engineeri...

Milliradian: The milliradian (mrad) is one thousandth of a radian.It is widely used in ballistics, laser alignment, optical engineering, and instrumentation.
