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 Square Nautical Miles
A square nautical mile (nmi²) equals the area of a square with sides of one nautical mile (1,852 m), giving approximately 3,429,904 m² - about 343 hectares. This unit is used in maritime and aviation contexts to describe patrol zones, territorial extents, and maritime boundaries. Exclusive Economic Zones (EEZs) and military operating areas are often quoted in square nautical miles. One square nautical mile is approximately 1.32 square statute miles.
