Convert Nanometer to Kilometer
Unit definitions
Nanometer
$\frac{1}{10^{9}}$ of a meter is a nanometer.
Kilometer
A kilometer is $1\,000$ meters in length.
How to convert Nanometer to Kilometer
$$\text{Length}_{\text{km}} = \frac{\text{Length}_{\text{nm}}}{{10}^{12}}$$
Examples
Example 1
Convert $40.0\ \text{nm}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = \frac{40.0}{{10}^{12}}$$
$$\text{Length}_{\text{km}} = 0.00000000004$$
$$\therefore \ 40.0\ \text{nm} = 0.00000000004 \ \text{km}$$
Example 2
Convert $60.0\ \text{nm}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = \frac{60.0}{{10}^{12}}$$
$$\text{Length}_{\text{km}} = 0.00000000006$$
$$\therefore \ 60.0\ \text{nm} = 0.00000000006 \ \text{km}$$
Example 3
Convert $100.0\ \text{nm}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = \frac{100.0}{{10}^{12}}$$
$$\text{Length}_{\text{km}} = 0.0000000001$$
$$\therefore \ 100.0\ \text{nm} = 0.0000000001 \ \text{km}$$
Example 4
Convert $145.0\ \text{nm}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = \frac{145.0}{{10}^{12}}$$
$$\text{Length}_{\text{km}} = 0.000000000145$$
$$\therefore \ 145.0\ \text{nm} = 0.000000000145 \ \text{km}$$
Example 5
Convert $165.0\ \text{nm}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = \frac{165.0}{{10}^{12}}$$
$$\text{Length}_{\text{km}} = 0.000000000165$$
$$\therefore \ 165.0\ \text{nm} = 0.000000000165 \ \text{km}$$
