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.
Plaza (plaza)
A plaza is a traditional Spanish area unit, historically used in various regions of Latin America and Spain. Its value varied widely by locality—commonly ranging between 2,700 and 3,000 square meters—depending on the colonial or municipal standards in effect at the time. The plaza's origin is linked to urban planning under Spanish colonial rule. Town centers in Spanish America were often designed around a central plaza, and surrounding parcels were measured using plaza-based units, embedding the measurement into the cultural fabric of settlement. In agricultural contexts, plazas were sometimes used to define modest landholdings such as gardens, homestead plots, or small fields. While largely replaced by metric units today, the plaza remains significant in historical cartography, land deeds, and anthropological studies of Iberian and colonial town development. It stands as a reminder that measurements often evolve out of cultural-practical needs rather than pure geometric abstraction.
