What is a circle?
One circle, as a unit of angle, means a complete trip around the center: 360 degrees. It is the same size as a revolution or a turn, just named differently.
Treating a whole circle as the unit is useful when you care about fractions of a rotation — a half circle, a third of a circle — rather than a count of degrees.
