Conversion derivation

Express both cm2 and mi2 in the same base unit m2 (square meter), then cancel the shared base unit.

1. 1

   Rewrite cm2 in the base unit

   $$1cm2=0.0001m2$$
2. 2

   Rewrite mi2 in the base unit

   $$1mi2=2,589,988.11m2$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1cm2& =\frac{0.0001\cancel{m2}}{2,589,988.11\cancel{m2}}\times 1mi2\\ & =\frac{0.0001}{2,589,988.11}mi2\\ & =3.86102159\times 10^{-11}mi2\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1mi2& =\frac{2,589,988.11\cancel{m2}}{0.0001\cancel{m2}}\times 1cm2\\ & =\frac{2,589,988.11}{0.0001}cm2\\ & =2.58998811\times 10^{10}cm2\end{array}$$
