How to convert Foot per second to Knot
$$\text{Speed}_{\text{kn}} = \text{Speed}_{\text{fts⁻¹}} \cdot 0.5924838012958963282937365010799136$$
Examples
Example 1
Convert $30.0\ \text{fts⁻¹}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 30.0 \cdot 0.5924838012958963282937365010799136$$
$$\text{Speed}_{\text{kn}} = 17.774514$$
$$\therefore \ 30.0\ \text{fts⁻¹} = 17.774514 \ \text{kn}$$
Example 2
Convert $80.0\ \text{fts⁻¹}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 80.0 \cdot 0.5924838012958963282937365010799136$$
$$\text{Speed}_{\text{kn}} = 47.398704$$
$$\therefore \ 80.0\ \text{fts⁻¹} = 47.398704 \ \text{kn}$$
Example 3
Convert $105.0\ \text{fts⁻¹}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 105.0 \cdot 0.5924838012958963282937365010799136$$
$$\text{Speed}_{\text{kn}} = 62.210799$$
$$\therefore \ 105.0\ \text{fts⁻¹} = 62.210799 \ \text{kn}$$
Example 4
Convert $150.0\ \text{fts⁻¹}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 150.0 \cdot 0.5924838012958963282937365010799136$$
$$\text{Speed}_{\text{kn}} = 88.87257$$
$$\therefore \ 150.0\ \text{fts⁻¹} = 88.87257 \ \text{kn}$$
Example 5
Convert $180.0\ \text{fts⁻¹}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 180.0 \cdot 0.5924838012958963282937365010799136$$
$$\text{Speed}_{\text{kn}} = 106.647084$$
$$\therefore \ 180.0\ \text{fts⁻¹} = 106.647084 \ \text{kn}$$
