The virgate, yardland, or yard of land (Latin: virgāta [terrae]) was an English unit of land. Primarily a measure of tax assessment rather than area, the virgate was usually (but not always) reckoned as 1⁄4 hide and notionally (but seldom exactly) equal to 30 acres. It was equivalent to two of the Danelaw's oxgangs.
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.
