Angle conversion, the angle system is an example of using hexadecimal.
It is specified that 1/360 of the circumferential angle is an angle of 1 degree, and the unit system that uses degrees as the unit to measure the angle is called the angle system.
Note that "degree" is a unit, not "1 degree", because the definition of a unit is the name of the standard quantity for measuring things.
