Encyclopedia > Square megametre

Square megametre (symbol Mm2) is an SI unit of surface area. It is one of the SI derived units.


1 Mm2 is equal to:

  • the area of a square measuring 1 megametre on each side
  • 1 000 000 000 000 m2
  • 100 000 000 hectares
  • 1 000 000 km2

Square megametres are not widely used; however, there are a number of "megametre fans" who think that this unit is very convenient for measuring oceans and continents.

  • 1 Mm2 is the area of Egypt
  • The area of Africa is 30.2 Mm2
  • The total area of the Moon's surface is 38 Mm2
  • The total area of dry land on Earth is 149.8 Mm2
