About Square Nanometers
A square nanometer (nm²) is an extraordinarily small unit of area - the area of a square with sides just one billionth of a meter. At this scale we measure individual molecules and atomic structures. The cross-section of a DNA double helix is roughly 20 nm², and modern transistor gates in cutting-edge microchips have areas measured in tens of nm². Square nanometers are essential in nanotechnology, semiconductor fabrication, surface chemistry, and scanning-tunnelling microscopy.
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.
