Unit definitions
Speed of sound at 20 degrees Celsius
The speed of sound in air is $343.21\ \text{m/s}$ at 20 degrees Celsius.
Kilometer per second
Kilometer per second is the distance traveled in kilometers in one second.
How to convert Speed of sound at 20 degrees Celsius to Kilometer per second
$$\text{Speed}_{\text{km/s}} = \text{Speed}_{\text{Speed of sound₂₀}} \cdot 0.34321$$
Examples
Example 1
Convert $45.0\ \text{Speed of sound₂₀}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 45.0 \cdot 0.34321$$
$$\text{Speed}_{\text{km/s}} = 15.44445$$
$$\therefore \ 45.0\ \text{Speed of sound₂₀} = 15.44445 \ \text{km/s}$$
Example 2
Convert $60.0\ \text{Speed of sound₂₀}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 60.0 \cdot 0.34321$$
$$\text{Speed}_{\text{km/s}} = 20.5926$$
$$\therefore \ 60.0\ \text{Speed of sound₂₀} = 20.5926 \ \text{km/s}$$
Example 3
Convert $120.0\ \text{Speed of sound₂₀}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 120.0 \cdot 0.34321$$
$$\text{Speed}_{\text{km/s}} = 41.1852$$
$$\therefore \ 120.0\ \text{Speed of sound₂₀} = 41.1852 \ \text{km/s}$$
Example 4
Convert $150.0\ \text{Speed of sound₂₀}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 150.0 \cdot 0.34321$$
$$\text{Speed}_{\text{km/s}} = 51.4815$$
$$\therefore \ 150.0\ \text{Speed of sound₂₀} = 51.4815 \ \text{km/s}$$
Example 5
Convert $185.0\ \text{Speed of sound₂₀}$ to $\text{km/s}$.
$$\text{Speed}_{\text{km/s}} = 185.0 \cdot 0.34321$$
$$\text{Speed}_{\text{km/s}} = 63.49385$$
$$\therefore \ 185.0\ \text{Speed of sound₂₀} = 63.49385 \ \text{km/s}$$
