mph から knot 変換ツール - マイル毎時 から ノット

Conversion derivation

Express both mph and knot 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 knot in the base unit

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

   Forward conversion

   $$\begin{array}{rl}1\mathrm{mph}& =\frac{0.44704\cancel{m/s}}{0.514444\cancel{m/s}}\times 1\mathrm{knot}\\ & =\frac{0.44704}{0.514444}\mathrm{knot}\\ & =0.868976992637\mathrm{knot}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{knot}& =\frac{0.514444\cancel{m/s}}{0.44704\cancel{m/s}}\times 1\mathrm{mph}\\ & =\frac{0.514444}{0.44704}\mathrm{mph}\\ & =1.15077845383\mathrm{mph}\end{array}$$
