in/s vers knot convertisseur - Pouce par Seconde vers Nœud

Conversion derivation

Express both in/s and knot 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 knot in the base unit

   $$1\mathrm{knot}=0.514444m/s$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1in/s& =\frac{0.0254\cancel{m/s}}{0.514444\cancel{m/s}}\times 1\mathrm{knot}\\ & =\frac{0.0254}{0.514444}\mathrm{knot}\\ & =0.049373692763\mathrm{knot}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{knot}& =\frac{0.514444\cancel{m/s}}{0.0254\cancel{m/s}}\times 1in/s\\ & =\frac{0.514444}{0.0254}in/s\\ & =20.2537007874in/s\end{array}$$
