What is Arcminute?

The arcminute is one-sixtieth of a degree, symbolized by a prime mark. In astronomy, the apparent diameter of the full Moon is about 31 arcminutes. The definition of 20/20 vision (visual acuity 1.0) is based on the ability to resolve details of one arcminute. Geographic coordinates are often expressed in degrees, minutes, and seconds, where one arcminute of latitude corresponds to approximately 1.852 km (one nautical mile) on Earth's surface.

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.
