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 Millimeters
A square millimeter (mm²) is a metric unit of area equal to a square with sides of one millimeter. It is commonly used in precision engineering, electronics, and measuring very small surfaces such as microchips or printed circuit boards. To visualise: a typical pinhead has an area of about 2-3 mm². This unit is essential in microscopy, medical imaging, and manufacturing where tiny, precise measurements are critical.
