About these units
Square Kilometer (km²)
A square kilometer equals one million square meters and is the standard unit for expressing large land areas, especially in geography, ecology, national planning, and environmental science. Countries, cities, national parks, forests, wetlands, and even ocean surface regions are frequently described in km². Because it provides a manageable scale for features too large for hectares or acres, it is widely used in atlases, scientific papers, and government reports. The square kilometer also plays a major role in ecology, where species ranges, habitat fragmentation, and conservation zones are measured using this unit. In geopolitics, km² help define national borders and territorial claims, making it a powerful instrument of scientific and political discourse.
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.
