Unit definitions

Speed of sound rounded

The speed of sound is frequently rounded to $340\ \text{m/s}$ in introductory physics calculations.

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 rounded to Knot

$$\text{Speed}_{\text{kn}} = \text{Speed}_{\text{Speed of sound}} \cdot 660.9071274298056155507559395248380$$

Examples

Example 1

Convert $35.0\ \text{Speed of sound}$ to $\text{kn}$.

$$\text{Speed}_{\text{kn}} = 35.0 \cdot 660.9071274298056155507559395248380$$

$$\text{Speed}_{\text{kn}} = 23131.74946$$

$$\therefore \ 35.0\ \text{Speed of sound} = 23131.74946 \ \text{kn}$$

Example 2

Convert $85.0\ \text{Speed of sound}$ to $\text{kn}$.

$$\text{Speed}_{\text{kn}} = 85.0 \cdot 660.9071274298056155507559395248380$$

$$\text{Speed}_{\text{kn}} = 56177.105832$$

$$\therefore \ 85.0\ \text{Speed of sound} = 56177.105832 \ \text{kn}$$

Example 3

Convert $120.0\ \text{Speed of sound}$ to $\text{kn}$.

$$\text{Speed}_{\text{kn}} = 120.0 \cdot 660.9071274298056155507559395248380$$

$$\text{Speed}_{\text{kn}} = 79308.855292$$

$$\therefore \ 120.0\ \text{Speed of sound} = 79308.855292 \ \text{kn}$$

Example 4

Convert $135.0\ \text{Speed of sound}$ to $\text{kn}$.

$$\text{Speed}_{\text{kn}} = 135.0 \cdot 660.9071274298056155507559395248380$$

$$\text{Speed}_{\text{kn}} = 89222.462203$$

$$\therefore \ 135.0\ \text{Speed of sound} = 89222.462203 \ \text{kn}$$

Example 5

Convert $180.0\ \text{Speed of sound}$ to $\text{kn}$.

$$\text{Speed}_{\text{kn}} = 180.0 \cdot 660.9071274298056155507559395248380$$

$$\text{Speed}_{\text{kn}} = 118963.282937$$

$$\therefore \ 180.0\ \text{Speed of sound} = 118963.282937 \ \text{kn}$$
