The "vara conuquera cuadrada" is another historical unit of land area measurement used in some Spanish-speaking countries, particularly in parts of Latin America. Like the "vara castellana cuadrada," it measures land area in square varas, but it is a regional variation and not part of the standard metric system.
The exact length of the "vara conuquera cuadrada" can vary by region, but it is generally close to 100 square varas, with each square vara having a specific length determined locally. The term "conuquera" is associated with the conuco, a type of small-scale agricultural plot traditionally used in some Latin American countries for subsistence farming.
As with other historical units of measurement, the use of the "vara conuquera cuadrada" is not standardized and is mostly a part of local customs and traditions. Official land measurements and land records in many Spanish-speaking countries have transitioned to more standardized systems, such as metric units, for land area measurements.
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.
