mph から in/s 変換ツール - マイル毎時 から インチ毎秒

Conversion derivation

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

1. 1

   Rewrite mph in the base unit

   $$1\mathrm{mph}=0.44704m/s$$
2. 2

   Rewrite in/s in the base unit

   $$1in/s=0.0254m/s$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{mph}& =\frac{0.44704\cancel{m/s}}{0.0254\cancel{m/s}}\times 1in/s\\ & =\frac{0.44704}{0.0254}in/s\\ & =17.6in/s\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1in/s& =\frac{0.0254\cancel{m/s}}{0.44704\cancel{m/s}}\times 1\mathrm{mph}\\ & =\frac{0.0254}{0.44704}\mathrm{mph}\\ & =0.056818181818\mathrm{mph}\end{array}$$
