Converting from Knot (kn) to Speed of Sound in Water (ssiw)

What is Knot (kn)

A knot (kn) is a unit of speed commonly used in maritime and aviation contexts. It is defined as one nautical mile per hour. One nautical mile is equivalent to 1.15078 miles or about 1.852 kilometers. Due to its widespread use, especially in navigation, understanding knots is essential for sailors, pilots, and anyone involved in marine or aerial activities.

What is Speed of Sound in Water (ssiw)

The speed of sound in water (ssiw) refers to how quickly sound waves travel through water. This speed can vary based on several factors, including temperature, salinity, and pressure. Typically, at a temperature of 25 degrees Celsius, the speed of sound in pure water is approximately 1482 meters per second. This property is crucial in fields like underwater acoustics, marine biology, and oceanography.

Conversion Formulas

To convert knots to the speed of sound in water, you can use the following formulas:

• From knots (kn) to speed of sound in water (ssiw):

  ssiw=kn×0.0003471285

• From speed of sound in water (ssiw) to knots (kn):

  kn=ssiw×2880.778

Examples

1. Converting 1 Knot to Speed of Sound in Water:

ssiw=1kn×0.0003471285=0.0003471285ssiw

2. Converting 17 Knots to Speed of Sound in Water:

ssiw=17kn×0.0003471285=0.005901185ssiw

3. Converting 11 Knots to Speed of Sound in Water:

ssiw=11kn×0.0003471285=0.003818414ssiw

4. Converting 16 Knots to Speed of Sound in Water:

ssiw=16kn×0.0003471285=0.005554056ssiw

5. Converting 1 Speed of Sound in Water to Knots:

kn=1ssiw×2880.778=2880.778kn

6. Converting 17 Speed of Sound in Water to Knots:

kn=17ssiw×2880.778=48973.22kn

7. Converting 11 Speed of Sound in Water to Knots:

kn=11ssiw×2880.778=31688.55kn

8. Converting 16 Speed of Sound in Water to Knots:

kn=16ssiw×2880.778=46092.44kn
