cm/s から km/h 変換ツール - センチメートル毎秒 から キロメートル毎時

Conversion derivation

Express both cm/s and km/h in the same base unit m/s (meter per second), then cancel the shared base unit.

1. 1

   Rewrite cm/s in the base unit

   $$1cm/s=0.01m/s$$
2. 2

   Rewrite km/h in the base unit

   $$1km/h=0.277778m/s$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1cm/s& =\frac{0.01\cancel{m/s}}{0.277778\cancel{m/s}}\times 1km/h\\ & =\frac{0.01}{0.277778}km/h\\ & =0.0359999712km/h\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1km/h& =\frac{0.277778\cancel{m/s}}{0.01\cancel{m/s}}\times 1cm/s\\ & =\frac{0.277778}{0.01}cm/s\\ & =27.7778cm/s\end{array}$$
