Distance measured as factors of 60.

kwet is about 11mm. Next unit up is 60 kwets. Next unit up is 60×60 kwets.

Therefore measurements are written 10.15.39 or 3600+900+39 (4539 kwets) or 49959 millimeters or approx 163 feet 9 inches.

Great distances are measured by adding more numbers in front. Two sets of numbers are used in small construction, five is massive projects.
