How to Convert Hectares to Square Millimeters

Conversion factor:

1 ha=10000000000 mm21\,\text{ha} = 10000000000\,\mathrm{mm}^{2}

Inverse factor:

1 mm2=1×10−10 ha1\,\mathrm{mm}^{2} = 1 × 10^-10\,\text{ha}

Example

Convert 15 ha to mm²:

mm2=ha×10000000000\mathrm{mm}^{2} = \text{ha} \times 10000000000
mm2=15×10000000000\mathrm{mm}^{2} = 15 \times 10000000000
mm2=150000000000\mathrm{mm}^{2} = 150000000000
=150000000000 mm2= 150000000000 \, \mathrm{mm}^{2}
