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 Ares
An are (a) is a metric unit of area equal to 100 square meters (10 m × 10 m). Though less commonly used today, it served as an intermediate unit between square meters and hectares in the metric system. One are equals 0.01 hectares or about 119.6 yd². It is still occasionally used in some European countries for measuring medium-sized land plots, gardens, and vineyards. The dekameter-squared (dam²) is another name for the same unit.
