What Is This Tool?
This online unit converter allows you to transform speed values from millimeter per hour (mm/h), a unit often used for very slow speeds, into meter per second (m/s), the SI derived unit for speed and velocity. It is designed to assist in converting small-scale speed measurements into a standard unit compatible with scientific and engineering calculations.
How to Use This Tool?

Common Use Cases
-
Measuring precipitation intensity reported in millimeters per hour for meteorology and environmental studies.
-
Assessing material deposition or corrosion rates in manufacturing and surface engineering.
-
Monitoring extremely slow movements such as creep and subsidence in geotechnical and structural engineering.
-
Performing physics and kinematics calculations requiring speed in standard SI units.
-
Expressing fluid flow velocity and airspeed in fluid mechanics and aerodynamics.
Tips & Best Practices
-
Ensure you input the speed value in millimeter/hour for accurate conversion results.
-
Be aware that converted values in meter/second are very small decimal numbers due to the slow rates involved.
-
Handle the converted results carefully to maintain precision and avoid rounding errors.
-
Use appropriate unit context when interpreting very small speeds in meter/second.
-
Leverage conversion examples to verify your calculations whenever possible.
Limitations
-
Millimeter/hour measures extremely slow rates, so the resulting meter/second value is a very small decimal that may be less intuitive.
-
Precision management is necessary to avoid rounding errors when dealing with such small values.
-
Meter/second may not be the most practical unit for describing slow processes without proper unit context.
Frequently Asked Questions
-
What does millimeter per hour measure?
-
Millimeter per hour expresses a slow linear speed or change in length of one millimeter occurring over an hour, often used for slow rates like precipitation intensity or material wear.
-
Why convert millimeter/hour to meter/second?
-
Converting to meter/second standardizes slow speed measurements into the SI unit of speed, facilitating use in physics, engineering, scientific reporting, and calculations.
-
Are there any challenges with converting these units?
-
Yes, since millimeter/hour represents very slow speeds, converting yields very small decimal values in meter/second that require careful handling to avoid precision loss.
Key Terminology
-
Millimeter per hour (mm/h)
-
A unit of speed representing a linear change of one millimeter per hour, often used to quantify very slow motion or depth change over time.
-
Meter per second (m/s)
-
The SI derived unit of speed indicating the distance in meters traveled in one second; also used as velocity in vector contexts.
-
Precipitation intensity
-
Depth of rainfall or snowfall expressed in millimeters per hour.
