About Dunam

A dunam (also dönüm or donum) is a unit of land area equal to exactly 1,000 m², used across Turkey, Israel, Palestine, Jordan, Lebanon, Iraq, and former Ottoman Empire territories. One dunam equals one stremma and one decare. The modern metric dunam of 1,000 m² was standardised during the British Mandate period; older Ottoman dunams varied by region (approximately 919-1,600 m²). It remains the primary land measurement unit for agricultural and property records throughout the Middle East, with properties routinely listed in dunams in Israeli and Palestinian real estate.

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.
