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.
A rood is an old and largely obsolete unit of land area measurement. It was historically used in some English-speaking countries, particularly in the United Kingdom and Ireland, but it is not commonly used today, and its use in official measurements has been largely phased out.
In the traditional system, one rood is equal to one-quarter of an acre. This means that there are 4 roods in one acre. Converting to modern units, one rood is approximately 1,011.71 square meters (m²) or 0.101171 hectares (ha).
The term "rood" is often associated with medieval land measurement systems and was used in land and property transactions in the past. While it may occasionally appear in historical documents or literature, it is no longer a standard unit of measurement for land area in most countries.
