How do you convert rods to acres?

Answer 1

1 acre = 160 square rods

A rod is a linear measure equal to 5.5 yards, or 16.5 feet while an acre is a measure of area equal to 4840 square yards, or 43,560 square feet.

However, a "square" rod is equal to 30.25 square yards or 272.25 square feet, so you can convert "square" rods to acres by dividing 4840 by 30.25 yards (or 43,560 by 272.25 feet) to get the number of square rods per acre (160).

Since the square root of 160 is not an integer, a farm measurement might define one acre as 10 by 16 rods.
