Convert Kilometer to Micrometer
Unit definitions
Kilometer
A kilometer is $1\,000$ meters in length.
Micrometer
$\frac{1}{10^{6}}$ of a meter is a micrometer.
How to convert Kilometer to Micrometer
$$\text{Length}_{\text{μm}} = \text{Length}_{\text{km}} \cdot {10}^{9}$$
Examples
Example 1
Convert $20.0\ \text{km}$ to $\text{μm}$.
$$\text{Length}_{\text{μm}} = 20.0 \cdot {10}^{9}$$
$$\text{Length}_{\text{μm}} = 20000000000$$
$$\therefore \ 20.0\ \text{km} = 20000000000 \ \text{μm}$$
Example 2
Convert $75.0\ \text{km}$ to $\text{μm}$.
$$\text{Length}_{\text{μm}} = 75.0 \cdot {10}^{9}$$
$$\text{Length}_{\text{μm}} = 75000000000$$
$$\therefore \ 75.0\ \text{km} = 75000000000 \ \text{μm}$$
Example 3
Convert $105.0\ \text{km}$ to $\text{μm}$.
$$\text{Length}_{\text{μm}} = 105.0 \cdot {10}^{9}$$
$$\text{Length}_{\text{μm}} = 105000000000$$
$$\therefore \ 105.0\ \text{km} = 105000000000 \ \text{μm}$$
Example 4
Convert $145.0\ \text{km}$ to $\text{μm}$.
$$\text{Length}_{\text{μm}} = 145.0 \cdot {10}^{9}$$
$$\text{Length}_{\text{μm}} = 145000000000$$
$$\therefore \ 145.0\ \text{km} = 145000000000 \ \text{μm}$$
Example 5
Convert $185.0\ \text{km}$ to $\text{μm}$.
$$\text{Length}_{\text{μm}} = 185.0 \cdot {10}^{9}$$
$$\text{Length}_{\text{μm}} = 185000000000$$
$$\therefore \ 185.0\ \text{km} = 185000000000 \ \text{μm}$$
