How to Convert Square Kilometers to Square Miles

Conversion factor:

1 km2=0.3861 mi21\,\mathrm{km}^{2} = 0.3861\,\mathrm{mi}^{2}

Inverse factor:

1 mi2=2.58999 km21\,\mathrm{mi}^{2} = 2.58999\,\mathrm{km}^{2}

Example

Convert 15 km² to mi²:

mi2=km2×0.3861\mathrm{mi}^{2} = \mathrm{km}^{2} \times 0.3861
mi2=15×0.3861\mathrm{mi}^{2} = 15 \times 0.3861
mi2=5.79153\mathrm{mi}^{2} = 5.79153
=5.79153 mi2= 5.79153 \, \mathrm{mi}^{2}
