ha から cm² 変換ツール - ヘクタール から 平方センチメートル

Conversion derivation

Express both ha and cm² in the same base unit m² (square meter), then cancel the shared base unit.

1. 1

   Rewrite ha in the base unit

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

   Rewrite cm² in the base unit

   $$1\mathrm{c}{\mathrm{m}}^2=0.0001{\mathrm{m}}^2$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{ha}& =\frac{10,000\cancel{{\mathrm{m}}^2}}{0.0001\cancel{{\mathrm{m}}^2}}\times 1\mathrm{c}{\mathrm{m}}^2\\ & =\frac{10,000}{0.0001}\mathrm{c}{\mathrm{m}}^2\\ & =100,000,000\mathrm{c}{\mathrm{m}}^2\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{c}{\mathrm{m}}^2& =\frac{0.0001\cancel{{\mathrm{m}}^2}}{10,000\cancel{{\mathrm{m}}^2}}\times 1\mathrm{ha}\\ & =\frac{0.0001}{10,000}\mathrm{ha}\\ & =1\times 10^{-8}\mathrm{ha}\end{array}$$
