I know it's just a saying, but taken literally, "coming full circle" would mean the circumference. That is, going around in a circle.



actually, when a circle's diameter is 1, its circumference is π


I think "unit circle" means a circle with a radius of 1, not a diameter of 1: http://everobotics.org/projects/roboMagellan/img/UnitCircle....
