Before electronic calculators, converting square varas (at 1 vara = 32.8748 inches) to acres was a tedious job. But if 1 vara = 33 1/3 inches, 3 varas are exactly 100 inches, 36 varas are exactly 100 feet, and 108 varas are exactly 100 yards. An easy division and some shuffling of the decimal point do the job.
How many acres in a section? An acre measures 43,560 square feet which is roughly 208.71 feet on a side. A section (one square mile) measures 27,878,400 square feet. Divide 27,878,400 by 43,560 and that equals 640 acres in a section. A half (1/2) section is 320 acres.
