The 'standard' for counties, which I think was from the Michigan/Wisconsin land bill or act?? 1 mile sections comprised of 640 acres (1mile by 1 mile) Townships made up of a six by six mile square, (36 sections). Counties made up of 36 townships, (6twp x 6twp).
I think this also corresponds to Range # , TWP # in property descriptions, which are somewhat like longitude/latitude.
