Tips & Best Practices
-
Use this conversion only for sea water at about 20°C and 10 meters depth for accuracy.
-
Avoid applying this rate at different temperatures or depths without proper adjustment.
-
Interpret km/s values in the context of their typical usage in high-speed fields like astronomy.
-
Verify input units carefully before converting to avoid errors in scientific analysis.
Limitations
-
Conversion applies specifically to sea water conditions of 20°C temperature and 10 meters depth.
-
Variations in sea water temperature, salinity, and depth affect sound velocity and conversion accuracy.
-
Using this conversion outside its defined conditions may produce inaccurate results.
-
Expressing underwater acoustic speeds in km/s is uncommon except in specialized scientific contexts.
