Convert from pik to cuerda

Unit Definition (pik)
The pik is a traditional unit of distance in the Eastern Mediterranean and Near East. The pik varied considerably but a typical value is about 28 inches (71 centimeters). This is an "arm" unit, like the Italian braccio and the Russian arshin.

Unit Definition (cuerda)
The Cuerda is a traditional unit of distance in Guatemala, equal to 25 varas or about 21 meters (roughly 69 feet). Since cuerda means a cord or rope in Spanish, this unit probably arose as the length of a measuring rope. The cuerda is also used as an area measure equal to 1 square cuerda or 625 square varas; this is about 440 square meters or 527 square yards. Note that the cuerda is also a traditional unit of land area in Puerto Rico, as well as a volume measurement for firewood in Cuba.
