Conversion formula

km/h = m/h × 0.001

One meter per hour equals 0.001 kilometer per hour. Multiply your value in meter per hour by this factor to get kilometer per hour. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 meter per hour:
5 × 0.001 = 0.005 km/h

About these measurements

Speed is distance traveled per unit of time.

The base reference used here is the meter per second. One meter per hour is 0.0002777777778 base units; one kilometer per hour is 0.2777777778 base units.

Important distinctions

Mach is excluded because the speed of sound depends on medium and temperature.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
