Unit definitions
Foot per second
A foot is a unit of length equal to $0.304\,8 \ \text{m}$. Foot per second is the distance traveled in feet in one second.
Kilometer per second
Kilometer per second is the distance traveled in kilometers in one second.
How to convert Foot per second to Kilometer per second
$$\text{Speed}_{\text{km/s}} = \text{Speed}_{\text{fts⁻¹}} \cdot 0.0003048$$
Examples
Example 1
Convert $50.0\ \text{fts⁻¹}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 50.0 \cdot 0.0003048$$
$$\text{Speed}_{\text{km/s}} = 0.01524$$
$$\therefore \ 50.0\ \text{fts⁻¹} = 0.01524 \ \text{km/s}$$
Example 2
Convert $85.0\ \text{fts⁻¹}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 85.0 \cdot 0.0003048$$
$$\text{Speed}_{\text{km/s}} = 0.025908$$
$$\therefore \ 85.0\ \text{fts⁻¹} = 0.025908 \ \text{km/s}$$
Example 3
Convert $105.0\ \text{fts⁻¹}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 105.0 \cdot 0.0003048$$
$$\text{Speed}_{\text{km/s}} = 0.032004$$
$$\therefore \ 105.0\ \text{fts⁻¹} = 0.032004 \ \text{km/s}$$
Example 4
Convert $145.0\ \text{fts⁻¹}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 145.0 \cdot 0.0003048$$
$$\text{Speed}_{\text{km/s}} = 0.044196$$
$$\therefore \ 145.0\ \text{fts⁻¹} = 0.044196 \ \text{km/s}$$
Example 5
Convert $160.0\ \text{fts⁻¹}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 160.0 \cdot 0.0003048$$
$$\text{Speed}_{\text{km/s}} = 0.048768$$
$$\therefore \ 160.0\ \text{fts⁻¹} = 0.048768 \ \text{km/s}$$
