How to Convert Square Millimeters to Hectares

Conversion factor:

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

Inverse factor:

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

Example

Convert 15 mm² to ha:

ha=mm2×1×10−10\text{ha} = \mathrm{mm}^{2} \times 1 × 10^-10
ha=15×1×10−10\text{ha} = 15 \times 1 × 10^-10
ha=1.5×10−9\text{ha} = 1.5 × 10^-9
=1.5×10−9 ha= 1.5 × 10^-9 \, \text{ha}
