How to Convert Square Centimeters to Square Kilometers

Conversion factor:

1 cm2=1×10−10 km21\,\mathrm{cm}^{2} = 1 × 10^-10\,\mathrm{km}^{2}

Inverse factor:

1 km2=10000000000 cm21\,\mathrm{km}^{2} = 10000000000\,\mathrm{cm}^{2}

Example

Convert 15 cm² to km²:

km2=cm2×1×10−10\mathrm{km}^{2} = \mathrm{cm}^{2} \times 1 × 10^-10
km2=15×1×10−10\mathrm{km}^{2} = 15 \times 1 × 10^-10
km2=1.5×10−9\mathrm{km}^{2} = 1.5 × 10^-9
=1.5×10−9 km2= 1.5 × 10^-9 \, \mathrm{km}^{2}
