About Square Megameters
A square megameter (Mm²) equals the area of a square with sides of one million meters - 10¹² m², or one trillion square meters. At this scale we describe major geographic and planetary regions. The entire land surface of Earth is about 149 Mm², the Indian Ocean covers roughly 70 Mm², and the Sahara Desert spans approximately 9.2 Mm². Square megameters provide a convenient scale for comparing continent-sized areas without resorting to hundreds of millions of square kilometers.
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.
