Cuerda

The term "cuerda" (and "Spanish acre") refers to various units of measurement in some Spanish-speaking regions, including Spain, Puerto Rico, Guatemala, Cuba, and Paraguay.

In Puerto Rico, a cuerda is a traditional unit of land area, as nearly 3,930 square meters, or 4,700 square yards, 0.971 acre, or 0.393 hectare (ha). The precise conversion is 1 cuerda = 3,930.395625 m. The term "Spanish acre" instead has been used sometimes by mainlanders. A cuerda and an acre have often been treated as equal because they are nearly the same size.
