What Is This Tool?
This online converter transforms speed values measured in millimeter per hour (mm/h), a very slow speed unit, into foot per second (ft/s), a standard unit in US customary and Imperial systems. It assists users in switching between metric and Imperial units for accurate comparison and analysis.
How to Use This Tool?
-
Enter the speed value in millimeters per hour.
-
Select millimeter per hour as the original unit and foot per second as the target unit.
-
Click the convert button to see the equivalent value in foot per second.
Key Features
-
Converts from millimeter per hour (mm/h) to foot per second (ft/s).
-
Suitable for applications in engineering, geotechnics, meteorology, and manufacturing.
-
Provides clear unit definitions and context for both measurement units.
Examples
-
10 mm/h equals 9.1134441528142e-6 ft/s.
-
1000 mm/h equals 0.00091134441528142 ft/s.
Common Use Cases
-
Monitoring slow ground motions in geotechnical engineering.
-
Tracking corrosion or material deposition rates in manufacturing.
-
Measuring precipitation intensity such as rainfall or snowfall depths.
-
Converting metric speed measurements for physics and engineering studies using Imperial units.
Tips & Best Practices
-
Use this converter for very slow speed conversions to ensure unit consistency.
-
Consider measurement context to select appropriate units especially when values become very small.
-
Double-check converted values in critical engineering calculations.
Limitations
-
Converted speeds in foot per second will be very small due to the original unit representing slow rates.
-
This conversion is less suitable for high-speed data where other speed units are more appropriate.
-
Precision may be affected when working with extremely small converted values.
Frequently Asked Questions
-
What does millimeter per hour measure?
-
Millimeter per hour expresses very slow linear speeds, such as changes in length or depth happening over one hour.
-
Where is foot per second commonly used?
-
Foot per second is used mainly in the US customary and Imperial systems for speeds in ballistics, engineering flows, and general physics.
-
Why are converted values often very small?
-
Because millimeter per hour is a much slower unit compared to foot per second, the conversion results in very small numerical values.
Key Terminology
-
Millimeter per hour [mm/h]
-
A speed unit measuring change in length by one millimeter every hour, commonly used to quantify very slow linear rates or slow movements.
-
Foot per second [ft/s]
-
A speed unit in US customary and Imperial systems, representing one foot traveled in one second, equal to 0.3048 meters per second.
