1 km&2 is equal to:

Conversely:

  • 1 m&2 = 0.000 001 km&2

  • 1 hectare = 0.01 km&2

  • 1 Square Mile = 2.589 988 km&2

  • 1 acre = 0.004 047 km&2


Note: "km&2" means square kilometre and not kilo–square metre. For example, 3 km&2 is equal to 3 000 000 m&2 and not to 3000 m&2 (nor even 9 000 000 m&2). Thus, in the case of an area, the SI prefixes provide steps of a factor one million instead of one thousand.
