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.
Best Answer: An acre is approximately 211 ft x 211 ft it is a square unit of measure. One acre comprises 4,840 square yards, 43,560 square feet. A mile is 5,280 ft long it is a linear unit of measure. If you want to know measurements of an acre in square miles it is 211/5280 x 211/5280 square miles. An acre is much much smaller than a square mile.
