How to convert Em to Nautical mile
$$\text{Length}_{\text{nmi}} = \text{Length}_{\text{em}} \cdot 0.000002285817134629229661627069834413247$$
Examples
Example 1
Convert $30.0\ \text{em}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 30.0 \cdot 0.000002285817134629229661627069834413247$$
$$\text{Length}_{\text{nmi}} = 0.000069$$
$$\therefore \ 30.0\ \text{em} = 0.000069 \ \text{nmi}$$
Example 2
Convert $85.0\ \text{em}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 85.0 \cdot 0.000002285817134629229661627069834413247$$
$$\text{Length}_{\text{nmi}} = 0.000194$$

$$\text{Length}_{\text{nmi}} = 0.000309$$
$$\therefore \ 135.0\ \text{em} = 0.000309 \ \text{nmi}$$
Example 5
Convert $175.0\ \text{em}$ to $\text{nmi}$.
$$\text{Length}_{\text{nmi}} = 175.0 \cdot 0.000002285817134629229661627069834413247$$
$$\text{Length}_{\text{nmi}} = 0.0004$$
$$\therefore \ 175.0\ \text{em} = 0.0004 \ \text{nmi}$$
