km/h 에서 in/s 변환기 - 킬로미터 매 시간 에서 인치 매 초

Conversion derivation

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

1. 1

   Rewrite km/h in the base unit

   $$1km/h=0.277778m/s$$
2. 2

   Rewrite in/s in the base unit

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

   Forward conversion

   $$\begin{array}{rl}1km/h& =\frac{0.277778\cancel{m/s}}{0.0254\cancel{m/s}}\times 1in/s\\ & =\frac{0.277778}{0.0254}in/s\\ & =10.9361417323in/s\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1in/s& =\frac{0.0254\cancel{m/s}}{0.277778\cancel{m/s}}\times 1km/h\\ & =\frac{0.0254}{0.277778}km/h\\ & =0.091439926848km/h\end{array}$$
