About Square Furlongs
A square furlong is an area unit equal to a square with sides of one furlong (220 yards or ~201.17 m), approximately 40,469 m² or exactly 10 acres. The furlong (from Old English 'furrow-long') was historically the standard ploughing distance, and 10 square furlongs equals one acre - a relationship that made traditional land surveying convenient. While square furlongs are rarely used in official modern measurements, they appear in historical land surveys, British horse racing contexts, and as a handy reference for visualising 10-acre blocks.
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.
