in/s 에서 ft/s 변환기 - 인치 매 초 에서 피트 매 초

Conversion derivation

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

1. 1

   Rewrite in/s in the base unit

   $$1in/s=0.0254m/s$$
2. 2

   Rewrite ft/s in the base unit

   $$1ft/s=0.3048m/s$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1in/s& =\frac{0.0254\cancel{m/s}}{0.3048\cancel{m/s}}\times 1ft/s\\ & =\frac{0.0254}{0.3048}ft/s\\ & =0.083333333333ft/s\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1ft/s& =\frac{0.3048\cancel{m/s}}{0.0254\cancel{m/s}}\times 1in/s\\ & =\frac{0.3048}{0.0254}in/s\\ & =12in/s\end{array}$$
