What is a gradian?
A unit that splits a right angle into 100 parts, so a full circle is 400 gradians and 90° is 100 grad. It shows up on surveying instruments.
What are arcminutes and arcseconds?
Fractions of a degree: 1° = 60 arcminutes (60′) = 3,600 arcseconds (3,600″). They are used for map coordinates and telescope precision.
What is a turn?
One full rotation: 360°, or 2π radians.
