cm² 에서 in² 변환기 - 제곱센티미터 에서 제곱인치

Conversion derivation

Express both cm² and in² in the same base unit m² (square meter), then cancel the shared base unit.

1. 1

   Rewrite cm² in the base unit

   $$1\mathrm{c}{\mathrm{m}}^2=0.0001{\mathrm{m}}^2$$
2. 2

   Rewrite in² in the base unit

   $$1\mathrm{i}{\mathrm{n}}^2=0.00064516{\mathrm{m}}^2$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{c}{\mathrm{m}}^2& =\frac{0.0001\cancel{{\mathrm{m}}^2}}{0.00064516\cancel{{\mathrm{m}}^2}}\times 1\mathrm{i}{\mathrm{n}}^2\\ & =\frac{0.0001}{0.00064516}\mathrm{i}{\mathrm{n}}^2\\ & =0.155000310001\mathrm{i}{\mathrm{n}}^2\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{i}{\mathrm{n}}^2& =\frac{0.00064516\cancel{{\mathrm{m}}^2}}{0.0001\cancel{{\mathrm{m}}^2}}\times 1\mathrm{c}{\mathrm{m}}^2\\ & =\frac{0.00064516}{0.0001}\mathrm{c}{\mathrm{m}}^2\\ & =6.4516\mathrm{c}{\mathrm{m}}^2\end{array}$$
