How to Convert Square Millimeters to Square Kilometers

Conversion factor:

1mm2=1×1012km21\,\mathrm{mm}^{2} = 1 × 10^-12\,\mathrm{km}^{2}

Inverse factor:

1km2=1000000000000mm21\,\mathrm{km}^{2} = 1000000000000\,\mathrm{mm}^{2}

Example

Convert 15 mm² to km²:

km2=mm2×1×1012\mathrm{km}^{2} = \mathrm{mm}^{2} \times 1 × 10^-12
km2=15×1×1012\mathrm{km}^{2} = 15 \times 1 × 10^-12
km2=1.5×1011\mathrm{km}^{2} = 1.5 × 10^-11
=1.5×1011km2= 1.5 × 10^-11 \, \mathrm{km}^{2}
