Nanometer
$\frac{1}{10^{9}}$ of a meter is a nanometer.
How to convert Millimeter to Nanometer
$$\text{Length}_{\text{nm}} = \text{Length}_{\text{mm}} \cdot {10}^{6}$$
Examples
Example 1
Convert $40.0\ \text{mm}$ to $\text{nm}$.
$$\text{Length}_{\text{nm}} = 40.0 \cdot {10}^{6}$$
$$\text{Length}_{\text{nm}} = 40000000$$
$$\therefore \ 40.0\ \text{mm} = 40000000 \ \text{nm}$$
Example 2
Convert $70.0\ \text{mm}$ to $\text{nm}$.
$$\text{Length}_{\text{nm}} = 70.0 \cdot {10}^{6}$$
$$\text{Length}_{\text{nm}} = 70000000$$
$$\therefore \ 70.0\ \text{mm} = 70000000 \ \text{nm}$$
Example 3
Convert $120.0\ \text{mm}$ to $\text{nm}$.
$$\text{Length}_{\text{nm}} = 120.0 \cdot {10}^{6}$$
$$\text{Length}_{\text{nm}} = 120000000$$
$$\therefore \ 120.0\ \text{mm} = 120000000 \ \text{nm}$$
Example 4
Convert $150.0\ \text{mm}$ to $\text{nm}$.
$$\text{Length}_{\text{nm}} = 150.0 \cdot {10}^{6}$$
$$\text{Length}_{\text{nm}} = 150000000$$
$$\therefore \ 150.0\ \text{mm} = 150000000 \ \text{nm}$$
Example 5
Convert $185.0\ \text{mm}$ to $\text{nm}$.
$$\text{Length}_{\text{nm}} = 185.0 \cdot {10}^{6}$$
$$\text{Length}_{\text{nm}} = 185000000$$
$$\therefore \ 185.0\ \text{mm} = 185000000 \ \text{nm}$$
