km² 에서 ha 변환기 - 제곱킬로미터 에서 헥타르

Conversion derivation

Express both km² and ha in the same base unit m² (square meter), then cancel the shared base unit.

1. 1

   Rewrite km² in the base unit

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

   Rewrite ha in the base unit

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

   Forward conversion

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

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{ha}& =\frac{10,000\cancel{{\mathrm{m}}^2}}{1,000,000\cancel{{\mathrm{m}}^2}}\times 1\mathrm{k}{\mathrm{m}}^2\\ & =\frac{10,000}{1,000,000}\mathrm{k}{\mathrm{m}}^2\\ & =0.01\mathrm{k}{\mathrm{m}}^2\end{array}$$
