Converting Speed of Sound in Water (ssiw) to Seconds per Kilometer (s/km)

What is Speed of Sound in Water (ssiw)

Speed of sound in water, often abbreviated as ssiw, refers to how fast sound waves travel through water. The speed varies based on temperature, salinity, and pressure, but it typically averages around 1482 meters per second in freshwater at 25 degrees Celsius. This property is crucial in various fields such as underwater acoustics, marine biology, and oceanography.

What is Seconds per Kilometer (s/km)

Seconds per kilometer (s/km) is a measure that expresses time in seconds required to travel one kilometer. This unit is commonly used in contexts like running, cycling, and swimming speed assessments. Lower values indicate faster speeds, as fewer seconds are needed to cover a kilometer.

Conversion Formulas

To convert between the speed of sound in water (ssiw) and seconds per kilometer (s/km), the following formulas can be used:

Examples

Let's see how to convert some example values between ssiw and s/km.

1. Example 1: Convert 1 ssiw to s/km. Using the formula, we find:

   s/km=1/(1∗0.6747638)≈1.484 s/km

2. Example 2: Convert 14 ssiw to s/km. Using the formula:

   s/km=1/(14∗0.6747638)≈0.04819742 s/km

3. Example 3: Convert 12 s/km to ssiw. Using the inverse formula:

   ssiw=1/(12∗0.6747638)≈0.05623032 ssiw

4. Example 4: Convert 16 s/km to ssiw.

   ssiw=1/(16∗0.6747638)≈0.04217274 ssiw

In each of these examples, the conversions illustrate how to seamlessly move between the two units using the defined relationships.
