About Square Miles
A square mile (mi²) is an imperial unit of area equal to a square with sides of one mile (5,280 ft × 5,280 ft). It is used for measuring large land areas like counties, states, and countries in the United States. Los Angeles covers about 503 mi², Rhode Island (smallest US state) is roughly 1,214 mi², and Alaska is about 665,384 mi². This unit is standard in American geography, land surveying, and regional planning.
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.
