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

   $$1\mathrm{ha}=10,000m2$$
2. 2

   Rewrite cm2 in the base unit

   $$1cm2=0.0001m2$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{ha}& =\frac{10,000\cancel{m2}}{0.0001\cancel{m2}}\times 1cm2\\ & =\frac{10,000}{0.0001}cm2\\ & =100,000,000cm2\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1cm2& =\frac{0.0001\cancel{m2}}{10,000\cancel{m2}}\times 1\mathrm{ha}\\ & =\frac{0.0001}{10,000}\mathrm{ha}\\ & =1\times 10^{-8}\mathrm{ha}\end{array}$$
