From Wikipedia, the free encyclopedia

Square kilometre, symbol km2, is a decimal multiple of the SI unit of surface area, the square metre, one of the SI derived units. 1 km2 is equal to:


  • 1 m2 = 0.000 001 (10−6) km2
  • 1 hectare = 0.01 (10−2) km2
  • 1 square mile = 2.589988km2
  • 1 acre = 0.004047km2, 0.4047ha or 4047 m2

Note: "km2" means (km)2, square kilometre or kilometre squared, and not k(m2), kilo–square metre. For example, 3 km2 is equal to 3×(1,000m)2 = 3,000,000 m2, not 3,000 m2.

The ISO symbol "km²" means "square kilometres" (not to be confused with "kilometres squared"). One of them contains 100 ha (hectares) and/or 1 million square metres (m²) and is a little over twice the size of Vatican City, just over half the size of Monaco (country ranked 192nd by area), and one-third of the size of the City of London.

The Imperial unit "square mile" contains approximately 2.5900 km².
