In mathematics, a degree is a common way to measure plane angle. It is written with the symbol ${\displaystyle ^{\circ }}$, where ${\displaystyle 360^{\circ }}$ corresponds to the entire circle.^[4][5][6]

It is not an SI unit. The SI uses radian to measure plane angle. However, according to the SI brochure, it is an accepted unit by SI.^[7]
