knot a km/h convertitore - Nodo a Chilometro all'ora

Conversion derivation

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

1. 1

   Rewrite knot in the base unit

   $$1\mathrm{knot}=0.514444m/s$$
2. 2

   Rewrite km/h in the base unit

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

   Forward conversion

   $$\begin{array}{rl}1\mathrm{knot}& =\frac{0.514444\cancel{m/s}}{0.277778\cancel{m/s}}\times 1km/h\\ & =\frac{0.514444}{0.277778}km/h\\ & =1.8519969184km/h\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1km/h& =\frac{0.277778\cancel{m/s}}{0.514444\cancel{m/s}}\times 1\mathrm{knot}\\ & =\frac{0.277778}{0.514444}\mathrm{knot}\\ & =0.539957701907\mathrm{knot}\end{array}$$
