-
Browser-based and easy to use.
Examples
-
1 Velocity of sound in sea water (20°C, 10 meter deep) = 1,521,600 mm/s
-
0.5 Velocity of sound in sea water (20°C, 10 meter deep) = 760,800 mm/s
Common Use Cases
-
Sonar ranging and depth sounding for navigation and obstacle detection.
-
Underwater communications and acoustic positioning in underwater vehicles.
-
Oceanographic acoustic measurements and instrument calibration.
-
Expressing sound speed in smaller metric units for precise engineering.
Tips & Best Practices
-
Ensure sea water conditions match 20°C and 10 meter depth before converting.
-
Use this unit conversion for precise measurement settings and calibration.
-
Avoid applying conversion to different temperatures or depths without adjustment.
-
Utilize millimeter per second units for low velocity and vibration measurements.
Limitations
-
Conversion rate is specific to 20°C and 10 meters depth sea water conditions.
-
Velocity of sound changes with temperature, salinity, and pressure beyond this context.
-
Millimeter per second unit may be impractical for very large distance or speed values.
Frequently Asked Questions
-
Why is the velocity of sound in sea water important?
-
It is critical for converting acoustic travel times into distances for marine navigation, communication, and measurement.
-
Can I use this conversion for sound speed at different depths or temperatures?
-
No, the conversion applies only to conditions at 20°C and 10 meters depth; applying it to other conditions requires corrections.
-
What is the millimeter per second unit used for?
-
It is used to describe very low speeds or vibration velocities in precision engineering and motion control.
Key Terminology
-
Velocity of sound in sea water (20°C, 10 meter deep)
-
The speed at which acoustic waves travel through seawater at 20°C and 10 meters depth, influenced by temperature, salinity, and pressure.
-
Millimeter per second [mm/s]
-
A metric speed unit denoting one millimeter traveled per second, used mainly for precise low-speed measurements and vibration velocity.
