How to convert Mile per second to Kilometer per second
$$\text{Speed}_{\text{km/s}} = \text{Speed}_{\text{mi/s}} \cdot 1.609344$$
Examples
Example 1
Convert $40.0\ \text{mi/s}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 40.0 \cdot 1.609344$$
$$\text{Speed}_{\text{km/s}} = 64.37376$$
$$\therefore \ 40.0\ \text{mi/s} = 64.37376 \ \text{km/s}$$
Example 2
Convert $90.0\ \text{mi/s}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 90.0 \cdot 1.609344$$
$$\text{Speed}_{\text{km/s}} = 144.84096$$
$$\therefore \ 90.0\ \text{mi/s} = 144.84096 \ \text{km/s}$$
Example 3
Convert $115.0\ \text{mi/s}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 115.0 \cdot 1.609344$$
$$\text{Speed}_{\text{km/s}} = 185.07456$$
$$\therefore \ 115.0\ \text{mi/s} = 185.07456 \ \text{km/s}$$
Example 4
Convert $135.0\ \text{mi/s}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 135.0 \cdot 1.609344$$
$$\text{Speed}_{\text{km/s}} = 217.26144$$
$$\therefore \ 135.0\ \text{mi/s} = 217.26144 \ \text{km/s}$$
Example 5
Convert $180.0\ \text{mi/s}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 180.0 \cdot 1.609344$$
$$\text{Speed}_{\text{km/s}} = 289.68192$$
$$\therefore \ 180.0\ \text{mi/s} = 289.68192 \ \text{km/s}$$
