Convert Speed of sound rounded to Kilometer per second
Unit definitions
Speed of sound rounded
The speed of sound is frequently rounded to $340\ \text{m/s}$ in introductory physics calculations.
Kilometer per second
Kilometer per second is the distance traveled in kilometers in one second.
How to convert Speed of sound rounded to Kilometer per second
$$\text{Speed}_{\text{km/s}} = \text{Speed}_{\text{Speed of sound}} \cdot 0.34$$
Examples
Example 1
Convert $45.0\ \text{Speed of sound}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 45.0 \cdot 0.34$$
$$\text{Speed}_{\text{km/s}} = 15.3$$
$$\therefore \ 45.0\ \text{Speed of sound} = 15.3 \ \text{km/s}$$
Example 2
Convert $80.0\ \text{Speed of sound}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 80.0 \cdot 0.34$$
$$\text{Speed}_{\text{km/s}} = 27.2$$
$$\therefore \ 80.0\ \text{Speed of sound} = 27.2 \ \text{km/s}$$
Example 3
Convert $100.0\ \text{Speed of sound}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 100.0 \cdot 0.34$$
$$\text{Speed}_{\text{km/s}} = 34$$
$$\therefore \ 100.0\ \text{Speed of sound} = 34 \ \text{km/s}$$
Example 4
Convert $145.0\ \text{Speed of sound}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 145.0 \cdot 0.34$$
$$\text{Speed}_{\text{km/s}} = 49.3$$
$$\therefore \ 145.0\ \text{Speed of sound} = 49.3 \ \text{km/s}$$
Example 5
Convert $185.0\ \text{Speed of sound}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 185.0 \cdot 0.34$$
$$\text{Speed}_{\text{km/s}} = 62.9$$
$$\therefore \ 185.0\ \text{Speed of sound} = 62.9 \ \text{km/s}$$
