Square kilometre (U.S. spelling:
square kilometer), symbol
km^{2}, is a decimal multiple of the
SI unit of
surface area, the square metre, one of the SI derived
units.1 km
^{2} is equal to:
Conversely:
- 1 m^{2} = 0.000 001 (10^{−6})
km^{2}
- 1 hectare = 0.01 (10^{−2}) km^{2}
- 1 square mile =
- 1 acre = , or 4047nbsp;m^{2}
Note: "km
^{2}" means (km)
^{2}, square kilometre or
kilometre squared, and not k(m
^{2}), kilo–square metre. For
example, 3 km
^{2} is equal to =
3,000,000 m
^{2}, not 3,000 m
^{2}.
