What is Turn?

The turn represents one complete rotation, equal to 360 degrees, 2 pi radians, or 400 gradians. It is the most intuitive angular unit in everyday language: a "half turn" is 180 degrees, and a "quarter turn" is 90 degrees. In sports, figure skating jumps are described in turns (a triple axel is 3.5 turns), and skateboard tricks use 360 for one full rotation. In engineering, rotational speed in RPM is based on the turn.

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.
