How to convert Foot to Nautical mile
$$\text{Length}_{\text{nmi}} = \text{Length}_{\text{ft}} \cdot 0.0001645788336933045356371490280777538$$
Examples
Example 1
Convert $30.0\ \text{ft}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 30.0 \cdot 0.0001645788336933045356371490280777538$$
$$\text{Length}_{\text{nmi}} = 0.004937$$
$$\therefore \ 30.0\ \text{ft} = 0.004937 \ \text{nmi}$$
Example 2
Convert $80.0\ \text{ft}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 80.0 \cdot 0.0001645788336933045356371490280777538$$
$$\text{Length}_{\text{nmi}} = 0.013166$$
$$\therefore \ 80.0\ \text{ft} = 0.013166 \ \text{nmi}$$
Example 3
Convert $110.0\ \text{ft}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 110.0 \cdot 0.0001645788336933045356371490280777538$$
$$\text{Length}_{\text{nmi}} = 0.018104$$
$$\therefore \ 110.0\ \text{ft} = 0.018104 \ \text{nmi}$$
Example 4
Convert $150.0\ \text{ft}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 150.0 \cdot 0.0001645788336933045356371490280777538$$
$$\text{Length}_{\text{nmi}} = 0.024687$$
$$\therefore \ 150.0\ \text{ft} = 0.024687 \ \text{nmi}$$
Example 5
Convert $165.0\ \text{ft}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 165.0 \cdot 0.0001645788336933045356371490280777538$$
$$\text{Length}_{\text{nmi}} = 0.027156$$
$$\therefore \ 165.0\ \text{ft} = 0.027156 \ \text{nmi}$$
