The "square foot (US survey)" is a unit of area used in the United States primarily for land surveying and mapping purposes. It differs from the standard square foot because it 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 foot (US survey) is equal to approximately 0.0929034119223 square meters (m²) or about 0.111111 square yards (yd²).
This unit is used in various land-related applications, particularly in the United States, where the U.S. survey foot and the square foot (US survey) are still employed for legal and historical reasons in certain land surveys and property descriptions. It's essential to be aware of the specific units being used when dealing with land measurements to avoid any discrepancies or errors.
A square rod is a unit of area measurement that is now considered obsolete and not commonly used in modern times. It was historically used in some English-speaking countries, including the United States and the United Kingdom, as part of the older system of land measurement.
One square rod is equal to an area of 1/160th of an acre or 1/4,840th of a square yard. In terms of square meters, one square rod is approximately equal to 25.29285264 square meters (m²).
The square rod was often used in land surveys and property descriptions in the past, but it has been largely replaced by more standardized systems of measurement. In modern times, square meters and square feet are the more commonly used units for measuring land area.
