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.
Cuerda (cuerda)
The cuerda is a traditional land unit used primarily in Puerto Rico, where it is legally defined as 3,930.395625 square meters—slightly smaller than a hectare and slightly larger than an acre. Cuerdas are widely used in real estate transactions, agriculture, and land management throughout the island. Farmland, forest preserves, and rural homesteads are typically measured in cuerdas rather than square meters or acreage. The cuerda's historical roots likely tie back to Spanish colonial surveying practices, but unlike many colonial units, the cuerda has been standardized, stabilized, and legally maintained well into the modern era. Its continued use reflects cultural identity as much as practicality; Puerto Ricans often conceptualize land parcels in cuerdas, making it a central part of the island's land-economy vocabulary.
