- Radian (rad): The standard unit of angular measure, used in many areas of mathematics. 1 rad ≈ 57.296°.
- Gradian (grad): Also known as gon, representing 1/400 of a full rotation.
- Turn (tr): A unit of plane angle equal to 360°, 2π rad, or 400 grads.
- Arcminute ('): 1/60 of a degree.
- Arcsecond (''): 1/60 of an arcminute.
