Converting from Seconds per mile (spm) to Speed of sound in water (ssiw) | Speed

What is Seconds per mile (spm)

Seconds per mile (spm) is a unit used to express the time taken for sound to travel one mile in water. It is commonly used in acoustics and underwater communication technologies.

What is Speed of sound in water (ssiw)

The Speed of sound in water (ssiw) is the speed at which sound waves propagate through water. It is influenced by factors such as temperature, pressure, and salinity of the water.
