Claim Text:
1. A hydrostatic level-measuring system for measuring with precision, a level normal to gravitation of a physical surface, comprising: a plurality of N water-holding cups containing water and fluidically interconnected with one another and resting upon the physical surface such that a top surface of said water within each said cup is stabilized into being substantially the same as the top surface of said water within all of the other said cups by virtue of the gravitation acting on said water and said water becoming equalized among said cups via said fluidic interconnections, where said N is greater than or equal to 2; each of said water-holding cups of comprising a cup height h a micrometer system for measuring on an absolute or relative scale, a distance d a level l by virtue of said micrometer system measuring each of said d
