About these units
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.
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.
