How to Convert Square Kilometers to Square Millimeters

Conversion factor:

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

Inverse factor:

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

Example

Convert 15 km² to mm²:

mm2=km2×1000000000000\mathrm{mm}^{2} = \mathrm{km}^{2} \times 1000000000000
mm2=15×1000000000000\mathrm{mm}^{2} = 15 \times 1000000000000
mm2=15000000000000\mathrm{mm}^{2} = 15000000000000
=15000000000000 mm2= 15000000000000 \, \mathrm{mm}^{2}
