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.

How to convert Knot to Speed of sound in fresh water at 20 degrees Celsius

$$\text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} = \text{Speed}_{\text{kn}} \cdot 0.0003473628929402055668092129942231225$$

Examples

Example 1

Convert $50.0\ \text{kn}$ to $\text{Speed of sound₂₀ (fresh water)}$.

$$\text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} = 50.0 \cdot 0.0003473628929402055668092129942231225$$

$$\text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} = 0.017368$$

$$\therefore \ 50.0\ \text{kn} = 0.017368 \ \text{Speed of sound₂₀ (fresh water)}$$

Example 2

Convert $70.0\ \text{kn}$ to $\text{Speed of sound₂₀ (fresh water)}$.

$$\text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} = 70.0 \cdot 0.0003473628929402055668092129942231225$$

$$\text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} = 0.024315$$

$$\therefore \ 70.0\ \text{kn} = 0.024315 \ \text{Speed of sound₂₀ (fresh water)}$$

Example 3

Convert $100.0\ \text{kn}$ to $\text{Speed of sound₂₀ (fresh water)}$.

$$\text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} = 100.0 \cdot 0.0003473628929402055668092129942231225$$

$$\text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} = 0.034736$$

$$\therefore \ 100.0\ \text{kn} = 0.034736 \ \text{Speed of sound₂₀ (fresh water)}$$

Example 4

Convert $130.0\ \text{kn}$ to $\text{Speed of sound₂₀ (fresh water)}$.

$$\text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} = 130.0 \cdot 0.0003473628929402055668092129942231225$$

$$\text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} = 0.045157$$

$$\therefore \ 130.0\ \text{kn} = 0.045157 \ \text{Speed of sound₂₀ (fresh water)}$$

Example 5

Convert $200.0\ \text{kn}$ to $\text{Speed of sound₂₀ (fresh water)}$.

$$\text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} = 200.0 \cdot 0.0003473628929402055668092129942231225$$

$$\text{Speed}_{\text{Speed of sound₂₀ (fresh water)}} = 0.069473$$

$$\therefore \ 200.0\ \text{kn} = 0.069473 \ \text{Speed of sound₂₀ (fresh water)}$$
