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

• 1 Mm2 is the area of Egypt
• The area of Africa is 30.2 Mm2
