How to convert US Survey foot to Nautical mile
$$\text{Length}_{\text{nmi}} = \text{Length}_{\text{sFT}} \cdot 0.0001645791628516302388976268233314004$$
Examples
Example 1
Convert $25.0\ \text{sFT}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 25.0 \cdot 0.0001645791628516302388976268233314004$$
$$\text{Length}_{\text{nmi}} = 0.004114$$
$$\therefore \ 25.0\ \text{sFT} = 0.004114 \ \text{nmi}$$
Example 2
Convert $75.0\ \text{sFT}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 75.0 \cdot 0.0001645791628516302388976268233314004$$
$$\text{Length}_{\text{nmi}} = 0.012343$$
$$\therefore \ 75.0\ \text{sFT} = 0.012343 \ \text{nmi}$$
Example 3
Convert $110.0\ \text{sFT}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 110.0 \cdot 0.0001645791628516302388976268233314004$$
$$\text{Length}_{\text{nmi}} = 0.018104$$
$$\therefore \ 110.0\ \text{sFT} = 0.018104 \ \text{nmi}$$
Example 4
Convert $130.0\ \text{sFT}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 130.0 \cdot 0.0001645791628516302388976268233314004$$
$$\text{Length}_{\text{nmi}} = 0.021395$$
$$\therefore \ 130.0\ \text{sFT} = 0.021395 \ \text{nmi}$$
Example 5
Convert $165.0\ \text{sFT}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 165.0 \cdot 0.0001645791628516302388976268233314004$$
$$\text{Length}_{\text{nmi}} = 0.027156$$
$$\therefore \ 165.0\ \text{sFT} = 0.027156 \ \text{nmi}$$
