About Square Chains
A square chain (ch²) is a surveying unit equal to the area of a square with sides of one Gunter's chain (66 feet or ~20.12 m), approximately 404.69 m². Ten square chains equal exactly one acre, making it the natural subdivision unit in traditional land surveying. The US Public Land Survey System used chains to lay out townships and sections, and square chains appear throughout old legal property descriptions and government land grants across North America. One square chain equals exactly 16 square rods.
About Feddan
A feddan (فدان) is the primary unit of land area in Egypt, Sudan, and parts of the Arab world, equal to approximately 4,200 m² (1.038 acres or 0.42 hectares). Its name derives from the Arabic word for 'yoke of oxen,' reflecting its agricultural origins - similar to the British acre. Egypt reports its cultivated farmland in millions of feddan; the fertile Nile Delta that feeds Egypt is measured in feddan. The feddan is subdivided into 24 kirats (each ~175 m²). It remains the legal standard for agricultural land registration in Egypt and Sudan.
