About these units
Square Nanometer (nm²)
A square nanometer represents 10⁻¹⁸ square meters and lies firmly within the realm of molecular and atomic structures. Protein surfaces, nanoparticle coatings, molecular binding sites, and atomic lattices are often described in nm². Researchers studying catalysts, DNA interactions, or graphene sheets depend on such units to express extremely small but functionally significant surface areas. Because nm² expresses areas where chemical reactivity is determined by single molecules or atomic clusters, it is fundamental in nanotechnology, materials engineering, and molecular chemistry.
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.
