How to convert Foot to Kilometer
$$\text{Length}_{\text{km}} = \text{Length}_{\text{ft}} \cdot 0.0003048$$
Examples
Example 1
Convert $30.0\ \text{ft}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 30.0 \cdot 0.0003048$$
$$\text{Length}_{\text{km}} = 0.009144$$
$$\therefore \ 30.0\ \text{ft} = 0.009144 \ \text{km}$$
Example 2
Convert $80.0\ \text{ft}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 80.0 \cdot 0.0003048$$
$$\text{Length}_{\text{km}} = 0.024384$$
$$\therefore \ 80.0\ \text{ft} = 0.024384 \ \text{km}$$
Example 3
Convert $110.0\ \text{ft}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 110.0 \cdot 0.0003048$$
$$\text{Length}_{\text{km}} = 0.033528$$
$$\therefore \ 110.0\ \text{ft} = 0.033528 \ \text{km}$$
Example 4
Convert $130.0\ \text{ft}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 130.0 \cdot 0.0003048$$
$$\text{Length}_{\text{km}} = 0.039624$$
$$\therefore \ 130.0\ \text{ft} = 0.039624 \ \text{km}$$
Example 5
Convert $200.0\ \text{ft}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 200.0 \cdot 0.0003048$$
$$\text{Length}_{\text{km}} = 0.06096$$
$$\therefore \ 200.0\ \text{ft} = 0.06096 \ \text{km}$$
