Unit definitions
Speed of sound in fresh water at 20 degrees Celsius
The speed of sound in fresh water is $1\ 481\ \text{m/s}$ at 20 degrees Celsius which is sligltly more than $4.3$ times the speed of sound in air at 20 degrees Celsius.
Kilometer per hour
Kilometer per hour is the distance traveled in kilometers in one hour.
How to convert Speed of sound in fresh water at 20 degrees Celsius to Kilometer per hour
$$\text{Speed}_{\text{kmh⁻¹}} = \text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} \cdot 5331.6$$
Examples
Example 1
Convert $30.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{kmh⁻¹}$.
$$\text{Speed}_{\text{kmh⁻¹}} = 30.0 \cdot 5331.6$$
$$\text{Speed}_{\text{kmh⁻¹}} = 159948$$
$$\therefore \ 30.0\ \text{Speed of sound₂₀ (fresh water)} = 159948 \ \text{kmh⁻¹}$$
Example 2
Convert $85.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{kmh⁻¹}$.
$$\text{Speed}_{\text{kmh⁻¹}} = 85.0 \cdot 5331.6$$
$$\text{Speed}_{\text{kmh⁻¹}} = 453186$$
$$\therefore \ 85.0\ \text{Speed of sound₂₀ (fresh water)} = 453186 \ \text{kmh⁻¹}$$
Example 3
Convert $100.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{kmh⁻¹}$.
$$\text{Speed}_{\text{kmh⁻¹}} = 100.0 \cdot 5331.6$$
$$\text{Speed}_{\text{kmh⁻¹}} = 533160$$
$$\therefore \ 100.0\ \text{Speed of sound₂₀ (fresh water)} = 533160 \ \text{kmh⁻¹}$$
Example 4
Convert $145.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{kmh⁻¹}$.
$$\text{Speed}_{\text{kmh⁻¹}} = 145.0 \cdot 5331.6$$
$$\text{Speed}_{\text{kmh⁻¹}} = 773082$$
$$\therefore \ 145.0\ \text{Speed of sound₂₀ (fresh water)} = 773082 \ \text{kmh⁻¹}$$
Example 5
Convert $185.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{kmh⁻¹}$.
$$\text{Speed}_{\text{kmh⁻¹}} = 185.0 \cdot 5331.6$$
$$\text{Speed}_{\text{kmh⁻¹}} = 986346$$
$$\therefore \ 185.0\ \text{Speed of sound₂₀ (fresh water)} = 986346 \ \text{kmh⁻¹}$$
