Which is based on the orbit of one planet around one star. I think the word is parochial.
Per Buckminster Fuller, it's all frequency and angle, plus some tetrahedrons (for sub-dividing volume) and precession (to establish chirality and the right-hand rule).
Edit: Bucky talked about parsing out [the problem], everything bigger than [the problem], and everything smaller than [the problem]. That scope determines the scale units. The breadth of the range determines the granularity of the measurements.
