What Is This Tool?
This online converter changes speeds from meter per hour (m/h), a unit for very slow velocities, into the local velocity of sound in seawater at 20°C and 10 meters deep. It helps relate slow mechanical displacements to marine acoustic velocity references.
How to Use This Tool?
-
Enter the value in meter/hour that you wish to convert.
-
Select meter/hour as the input unit and velocity of sound in sea water (20°C, 10 meter deep) as the target unit.
-
Start the conversion to get the equivalent speed expressed as a fraction of local sound velocity.
Key Features
-
Converts slow velocities from meter/hour to the velocity of sound in sea water (20°C, 10 m depth).
-
Provides a precise conversion factor relevant in underwater acoustic and oceanographic contexts.
-
Suitable for applications in sonar, underwater navigation, and acoustic positioning systems.
Examples
-
10 meter/hour [m/h] equals 1.8255637340811e-6 times the velocity of sound in sea water (20°C, 10 meter deep).
-
1000 meter/hour [m/h] corresponds to 1.8255637340811e-4 times the local seawater sound speed.
Common Use Cases
-
Expressing very slow conveyor or feed rates in manufacturing processes with hourly throughput.
-
Reporting gradual ground or structural movement such as slow landslides or building settlement per hour.
-
Converting physical displacements to equivalent sound-speed fractions for sonar ranging and underwater positioning.
-
Calibrating oceanographic acoustic instruments using local seawater sound speed references.
Tips & Best Practices
-
Confirm the environmental conditions match 20°C and approximately 10 meters depth for accurate context.
-
Use this conversion primarily for very slow speeds relevant in specialized acoustic or oceanographic settings.
-
Validate results with actual local sound-speed measurements when available for precise underwater applications.
Limitations
-
The sound velocity unit corresponds to specific temperature and depth; it may not apply accurately at different conditions.
-
Converted values are very small due to the disparity between slow meters/hour speeds and typical seawater sound speeds.
-
Meter/hour measures extremely slow motions, limiting the relevance of this conversion in fast or large-scale speed contexts.
Frequently Asked Questions
-
Why convert from meter/hour to velocity of sound in sea water?
-
It allows expressing slow linear velocities as fractions of local sound speed, useful in underwater navigation and acoustic measurements.
-
Does this conversion apply to all ocean depths and temperatures?
-
No. The conversion is specific to sea water at 20°C and a depth of 10 meters and may not be accurate elsewhere.
-
What are the typical applications of this conversion?
-
It is used in sonar ranging, underwater acoustic positioning, oceanographic measurements, and calibration of acoustic instruments.
Key Terminology
-
Meter/hour [m/h]
-

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, used for underwater acoustic referencing.
-
Sonar ranging
-
A method of determining distances underwater by measuring the time it takes for sound waves to travel.
