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 Inches
A square inch (in²) is an imperial unit of area equal to a square with sides of one inch (25.4 mm × 25.4 mm). It is commonly used in the United States for measuring small areas like fabric swatches, screen sizes, or printed materials. A standard business card is about 6 in², and a typical smartphone screen might be 15-20 in². This unit remains prevalent in American manufacturing, printing, and retail.
