What does Mach (SI standard) represent?

Mach is a dimensionless number representing the ratio of an object's speed to the local speed of sound in the surrounding medium, widely used in engineering and aerodynamics.

Why is the velocity of sound in sea water affected by temperature and depth?

Because sound speed in sea water is influenced by temperature, salinity, and pressure, which typically change with depth and environment.

Can I use this conversion for sound speeds measured in other conditions?

No, this conversion specifically applies to sea water at 20°C and 10 meters depth and may not be accurate for other conditions.
