A square rod (US survey) is a unit of area measurement used in the United States for land surveying and legal property descriptions. It is different from the standard square rod or square pole and is based on the U.S. survey foot, which is a historical unit of length used in land surveying in the United States. The U.S. survey foot is slightly different from the international foot.
One square rod (US survey) is equal to 1/160th of an acre. In terms of area, this is approximately equal to 25.29285264 square meters (m²) or 0.00625 acres.
This unit is used in land-related applications, especially in the United States, where the U.S. survey square rod is employed for legal and historical reasons in land surveys, property descriptions, and land records. It's important to be aware of the specific units being used when dealing with land measurements in the United States to avoid discrepancies or errors.
An acre (ac) is a unit of area commonly used in the United States and some other countries, especially for measuring land area, particularly in the context of real estate and agriculture.
One acre is equivalent to 43,560 square feet or 4,840 square yards. In terms of square meters, it is approximately 4,046.86 square meters.
To provide some perspective, an acre is roughly the size of a football field, excluding the end zones. It is a common unit for describing land area in rural and suburban areas, as well as for determining the size of plots of land, farms, and other land parcels.
