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.
About Square Micrometers
A square micrometer (μm²), also called a square micron, equals one trillionth of a square meter - the area of a square with sides one millionth of a meter (10⁻¹² m²). This is the natural scale of biological cells: a human red blood cell has a surface area of about 135 μm², and a typical bacterium might occupy 2-10 μm². Square micrometers are the standard unit in cell biology, histology, microscopy, and semiconductor characterisation where individual features on wafers are measured.
