How to Convert Square Feet to Square Kilometers

Conversion factor:

1 ft2=9.2903×10−8 km21\,\mathrm{ft}^{2} = 9.2903 × 10^-8\,\mathrm{km}^{2}

Inverse factor:

1 km2=10763915.05118 ft21\,\mathrm{km}^{2} = 10763915.05118\,\mathrm{ft}^{2}

Example

Convert 15 ft² to km²:

km2=ft2×9.2903×10−8\mathrm{km}^{2} = \mathrm{ft}^{2} \times 9.2903 × 10^-8
km2=15×9.2903×10−8\mathrm{km}^{2} = 15 \times 9.2903 × 10^-8
km2=0.00000139\mathrm{km}^{2} = 0.00000139
=0.00000139 km2= 0.00000139 \, \mathrm{km}^{2}
