This unit is Babylonian and is 1000/360. The Babylonians used it as 1/360 = 0.0027777777777777777777r and they also used the metre as the unit this unit is calculated against.
This unit is derived from an analysis of the mathematics of the eclipse.
3.666r / 0.0027777 = 1320 and this is 10 x 11 x 12. The unit was discoved probably, not invented. It appears to be evidence of intelligent design.
using the eclipse unit 14.666r gives 5280 being 4 x 10 x 11 x 12.
