Conversion derivation

Express both ft2 and ha in the same base unit m2 (square meter), then cancel the shared base unit.

1. 1

   Rewrite ft2 in the base unit

   $$1ft2=0.092903m2$$
2. 2

   Rewrite ha in the base unit

   $$1\mathrm{ha}=10,000m2$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1ft2& =\frac{0.092903\cancel{m2}}{10,000\cancel{m2}}\times 1\mathrm{ha}\\ & =\frac{0.092903}{10,000}\mathrm{ha}\\ & =0.0000092903\mathrm{ha}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{ha}& =\frac{10,000\cancel{m2}}{0.092903\cancel{m2}}\times 1ft2\\ & =\frac{10,000}{0.092903}ft2\\ & =107,639.150512ft2\end{array}$$
