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.
Knot
A nautical mile is a unit of length used in navigation and is equal to $1\,852$ meters. A knot is a unit of speed expressed in nautical miles per hour.
How to convert Speed of sound in fresh water at 20 degrees Celsius to Knot
$$\text{Speed}_{\text{kn}} = \text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} \cdot 2878.833693304535637149028077753780$$
Examples
Example 1
Convert $25.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 25.0 \cdot 2878.833693304535637149028077753780$$
$$\text{Speed}_{\text{kn}} = 71970.842333$$
$$\therefore \ 25.0\ \text{Speed of sound₂₀ (fresh water)} = 71970.842333 \ \text{kn}$$
Example 2
Convert $65.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 65.0 \cdot 2878.833693304535637149028077753780$$
$$\text{Speed}_{\text{kn}} = 187124.190065$$
$$\therefore \ 65.0\ \text{Speed of sound₂₀ (fresh water)} = 187124.190065 \ \text{kn}$$
Example 3
Convert $120.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 120.0 \cdot 2878.833693304535637149028077753780$$
$$\text{Speed}_{\text{kn}} = 345460.043197$$
$$\therefore \ 120.0\ \text{Speed of sound₂₀ (fresh water)} = 345460.043197 \ \text{kn}$$
Example 4
Convert $140.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 140.0 \cdot 2878.833693304535637149028077753780$$
$$\text{Speed}_{\text{kn}} = 403036.717063$$
$$\therefore \ 140.0\ \text{Speed of sound₂₀ (fresh water)} = 403036.717063 \ \text{kn}$$
Example 5
Convert $165.0\ \text{Speed of sound₂₀ (fresh water)}$ to $\text{kn}$.
$$\text{Speed}_{\text{kn}} = 165.0 \cdot 2878.833693304535637149028077753780$$
$$\text{Speed}_{\text{kn}} = 475007.559395$$
$$\therefore \ 165.0\ \text{Speed of sound₂₀ (fresh water)} = 475007.559395 \ \text{kn}$$
