square kilometre

Square kilometre (U.S. spelling: square kilometer), 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:

  • 1,000,000 m²
  • 100 ha (hectare)

Conversely:

  • 1 m² = 0.000 001 (10-6) km²
  • 1 hectare = 0.01 (10-2) km²
  • 1 square mile = 2.589 988 km²
  • 1 acre = 0.004 047 km², 40.47 ha 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 * (1,000 m)² = 3,000,000 m², not 3,000 m².

Comparative order

The [[1 E+6 m²|106 m²]] orders of magnitude page gives comparisons with geographic areas.

A hectare (104 m²) is less than a square kilometre which is less than a square megametre (1012 m²).
