About these units
Square Micrometer (µm²)
A square micrometer, also called a square micron, equals 10⁻¹² square meters. It is a fundamental unit in microbiology, nanotechnology, semiconductor physics, and materials characterization. Cells, organelles, thin films, and laser spot sizes are frequently measured in µm². In semiconductor fabrication, transistor gates, nanoscale features, and photolithographic patterns often have areas measured at this scale. At such dimensions, quantum effects, crystal lattice structures, and electron mobility become important, making µm² not just a geometric unit but a bridge to fundamental physical behavior at microscopic scales.
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.
