Convert millimeter/hour to kilometer/hour
Please provide values below to convert millimeter/hour [mm/h] to kilometer/hour [km/h], or Convert kilometer/hour to millimeter/hour.
1 mm/h = 1.00000000072e-06 km/h. To convert millimeter/hour to kilometer/hour, multiply the value by 1.00000000072e-06; to go the other way, divide by it (1 km/h = 999999.99928 mm/h). Both units measure speed and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mm/h = 1.00000000072e-06 km/h

Millimeter/hour
Millimeter per hour (mm/h) is a unit of measurement that indicates the rate of rainfall or precipitation, representing how many millimeters of water fall in one hour.
History/Origin
The millimeter per hour has been used in meteorology and hydrology to quantify rainfall intensity, especially with the advent of precise rain gauges and weather measurement tools in the 20th century.
Current Use
Today, mm/h is commonly used in weather forecasting, climate studies, and hydrological assessments to measure and communicate the intensity of rainfall events.
Kilometer/hour
Kilometer per hour (km/h) is a unit of speed expressing the number of kilometers traveled in one hour.
History/Origin
The km/h unit originated from the metric system, developed in France during the late 18th century, and became widely adopted for measuring speed in transportation and scientific contexts.
Current Use
Km/h is commonly used worldwide to specify vehicle speeds, speed limits, and other applications involving the measurement of speed in everyday life and transportation systems.
