mm2 から m2 変換ツール - 平方ミリメートル から 平方メートル

Conversion derivation

Express both mm2 and m2 in the same base unit m2 (square meter), then cancel the shared base unit.

1. 1

   Rewrite mm2 in the base unit

   $$1mm2=0.000001m2$$
2. 2

   Rewrite m2 in the base unit

   $$1m2=1m2$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1mm2& =\frac{0.000001\cancel{m2}}{1\cancel{m2}}\times 1m2\\ & =\frac{0.000001}{1}m2\\ & =0.000001m2\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1m2& =\frac{1\cancel{m2}}{0.000001\cancel{m2}}\times 1mm2\\ & =\frac{1}{0.000001}mm2\\ & =1,000,000mm2\end{array}$$
