1 m/s = 3.6 km/h

Calculated in your browser

Conversion formula

km/h = m/s × 3.6

One meter per second equals 3.6 kilometer per hour. Multiply your value in meter per second by this factor to get kilometer per hour. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 meter per second:
5 × 3.6 = 18 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 second is 1 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.

Common questions
