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.

What is Gradian?

The gradian, also called the gon, was introduced during the French Revolution alongside the metric system. It divides a right angle into 100 gradians, making a full circle 400 gradians. This unit is primarily used in surveying, especially in France and Germany, where survey instruments may be graduated in gradians. The advantage is that a right angle is exactly 100, simplifying slope calculations. One gradian equals 0.9 degrees.
