About these units
Square Mile (US Survey) (mi² (US))
The US survey square mile is extremely close to the international square mile but is defined using the US survey foot, a slightly different value than the international foot historically used in land surveying. This unit appears in American land deeds, cadastral maps, and federal land management documents. The Public Land Survey System (PLSS), which divided much of the western United States into townships and sections, relied heavily on survey-based square miles. Although the modern US has transitioned to the international foot (as of 2023), historical land descriptions remain legally tied to the survey-based definition, ensuring its continued relevance.
Varas Castellanas Cuad (v.c.c.)
A vara castellana cuadrada is the square form of the Castilian vara, an old Spanish unit of length. While the exact length of a vara historically ranged between regions, the commonly accepted Castilian value is 0.8359 meters. Thus, the square vara equals approximately 0.69875 square meters. Square varas were widely used in Spanish colonial land distribution across Latin America, including territories that later became the U.S. Southwest. Early ranchos, town grants, and agricultural holdings were often described using square varas. Because original surveys were conducted with ropes or rods rather than precise instruments, slight variations exist between historic definitions. Despite this, Spanish-era land patterns still rely on square vara conversions for legal clarification of old property descriptions. This unit provides essential insight into how colonial authorities organized land, particularly in regions with mixed indigenous and European land traditions.
