in² vers ha convertisseur - Pouce Carré vers Hectare

Conversion derivation

Express both in² and ha in the same base unit m² (square meter), then cancel the shared base unit.

1. 1

   Rewrite in² in the base unit

   $$1\mathrm{i}{\mathrm{n}}^2=0.00064516{\mathrm{m}}^2$$
2. 2

   Rewrite ha in the base unit

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

   Forward conversion

   $$\begin{array}{rl}1\mathrm{i}{\mathrm{n}}^2& =\frac{0.00064516\cancel{{\mathrm{m}}^2}}{10,000\cancel{{\mathrm{m}}^2}}\times 1\mathrm{ha}\\ & =\frac{0.00064516}{10,000}\mathrm{ha}\\ & =6.4516\times 10^{-8}\mathrm{ha}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{ha}& =\frac{10,000\cancel{{\mathrm{m}}^2}}{0.00064516\cancel{{\mathrm{m}}^2}}\times 1\mathrm{i}{\mathrm{n}}^2\\ & =\frac{10,000}{0.00064516}\mathrm{i}{\mathrm{n}}^2\\ & =15,500,031.0001\mathrm{i}{\mathrm{n}}^2\end{array}$$
