What is Degree?

The degree is the most commonly used unit of angle, with one full rotation divided into 360 degrees. This system is believed to originate from ancient Babylonian astronomy, where a year of roughly 360 days suggested dividing a circle into 360 parts. Degrees are used everywhere in daily life: compass bearings, slopes, architecture, and geometry. A right angle is 90 degrees, a straight angle is 180 degrees, and a full rotation is 360 degrees.

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.
