How to convert Inch to Kilometer
$$\text{Length}_{\text{km}} = \text{Length}_{\text{in}} \cdot 0.0000254$$
Examples
Example 1
Convert $20.0\ \text{in}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 20.0 \cdot 0.0000254$$
$$\text{Length}_{\text{km}} = 0.000508$$
$$\therefore \ 20.0\ \text{in} = 0.000508 \ \text{km}$$
Example 2
Convert $70.0\ \text{in}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 70.0 \cdot 0.0000254$$
$$\text{Length}_{\text{km}} = 0.001778$$
$$\therefore \ 70.0\ \text{in} = 0.001778 \ \text{km}$$
Example 3
Convert $100.0\ \text{in}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 100.0 \cdot 0.0000254$$
$$\text{Length}_{\text{km}} = 0.00254$$
$$\therefore \ 100.0\ \text{in} = 0.00254 \ \text{km}$$
Example 4
Convert $145.0\ \text{in}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 145.0 \cdot 0.0000254$$
$$\text{Length}_{\text{km}} = 0.003683$$
$$\therefore \ 145.0\ \text{in} = 0.003683 \ \text{km}$$
Example 5
Convert $175.0\ \text{in}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 175.0 \cdot 0.0000254$$
$$\text{Length}_{\text{km}} = 0.004445$$
$$\therefore \ 175.0\ \text{in} = 0.004445 \ \text{km}$$
