Conversion derivation

Express both ft2 and mm2 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

   $$1mm2=0.000001m2$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1ft2& =\frac{0.092903\cancel{m2}}{0.000001\cancel{m2}}\times 1mm2\\ & =\frac{0.092903}{0.000001}mm2\\ & =92,903mm2\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1mm2& =\frac{0.000001\cancel{m2}}{0.092903\cancel{m2}}\times 1ft2\\ & =\frac{0.000001}{0.092903}ft2\\ & =0.000010763915ft2\end{array}$$
