What is Milliradian?

The milliradian is one-thousandth of a radian, approximately 0.0573 degrees. It is widely used in military and shooting applications, where NATO standard scopes use milliradians for angular measurement. One mrad subtends approximately one meter at a distance of 1,000 meters, making range estimation intuitive. Laser beam divergence and optical aberrations are also often specified in milliradians.

What is Arcsecond?

The arcsecond is one-sixtieth of an arcminute, or one 3,600th of a degree. In astronomy, stellar parallax is measured in arcseconds, and one parsec (about 3.26 light-years) is defined as the distance at which a star shows a parallax of one arcsecond. In surveying, high-precision instruments achieve sub-arcsecond resolution. GPS coordinates expressed in degrees, minutes, and seconds use arcseconds for fine positional accuracy, where one arcsecond of latitude is approximately 31 meters on Earth's surface.
