How to convert Foot per hour to Knot
$$\text{Speed}_{\text{kn}} = \text{Speed}_{\text{ft/h}} \cdot 0.0001645788336933045356371490280777538$$
Examples
Example 1
Convert $20.0\ \text{ft/h}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 20.0 \cdot 0.0001645788336933045356371490280777538$$
$$\text{Speed}_{\text{kn}} = 0.003292$$
$$\therefore \ 20.0\ \text{ft/h} = 0.003292 \ \text{kn}$$
Example 2
Convert $90.0\ \text{ft/h}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 90.0 \cdot 0.0001645788336933045356371490280777538$$
$$\text{Speed}_{\text{kn}} = 0.014812$$
$$\therefore \ 90.0\ \text{ft/h} = 0.014812 \ \text{kn}$$
Example 3
Convert $100.0\ \text{ft/h}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 100.0 \cdot 0.0001645788336933045356371490280777538$$
$$\text{Speed}_{\text{kn}} = 0.016458$$
$$\therefore \ 100.0\ \text{ft/h} = 0.016458 \ \text{kn}$$
Example 4
Convert $145.0\ \text{ft/h}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 145.0 \cdot 0.0001645788336933045356371490280777538$$
$$\text{Speed}_{\text{kn}} = 0.023864$$
$$\therefore \ 145.0\ \text{ft/h} = 0.023864 \ \text{kn}$$
Example 5
Convert $190.0\ \text{ft/h}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 190.0 \cdot 0.0001645788336933045356371490280777538$$
$$\text{Speed}_{\text{kn}} = 0.03127$$
$$\therefore \ 190.0\ \text{ft/h} = 0.03127 \ \text{kn}$$
