mm² a ha convertidor - Milímetro cuadrado a Hectárea

Conversion derivation

Express both mm² and ha in the same base unit m² (square meter), then cancel the shared base unit.

1. 1

   Rewrite mm² in the base unit

   $$1\mathrm{m}{\mathrm{m}}^2=0.000001{\mathrm{m}}^2$$
2. 2

   Rewrite ha in the base unit

   $$1\mathrm{ha}=10,000{\mathrm{m}}^2$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{m}{\mathrm{m}}^2& =\frac{0.000001\cancel{{\mathrm{m}}^2}}{10,000\cancel{{\mathrm{m}}^2}}\times 1\mathrm{ha}\\ & =\frac{0.000001}{10,000}\mathrm{ha}\\ & =1\times 10^{-10}\mathrm{ha}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{ha}& =\frac{10,000\cancel{{\mathrm{m}}^2}}{0.000001\cancel{{\mathrm{m}}^2}}\times 1\mathrm{m}{\mathrm{m}}^2\\ & =\frac{10,000}{0.000001}\mathrm{m}{\mathrm{m}}^2\\ & =1\times 10^{10}\mathrm{m}{\mathrm{m}}^2\end{array}$$
