About these units
Square Perch (perch²)
A square perch is equivalent to a square rod, as "perch" was another historical name for a rod, used in various medieval and regional English measurement systems. Perches commonly appeared in church records, tithing assessments, and agricultural inventories. Because the perch was both a length and an area unit, it played dual roles in land taxation and construction. These overlapping terminologies—rod, pole, perch—reflect the organic evolution of measurement in medieval Europe, long before unified systems took hold.
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.
