How to convert meters per second to kilometers per hour
km/h = m/s × 3.6Multiply the value in meters per second by 3.6. To go the other way, multiply by 0.2777777778 (or divide by 3.6).
A meter per second is larger than a kilometer per hour: one meter per second contains 3.6 kilometers per hour.
Worked examples
- 1 meter per second1 m/s × 3.6 = 3.6 km/h
- 5 meters per second5 m/s × 3.6 = 18 km/h
- 10 meters per second10 m/s × 3.6 = 36 km/h
- 20 meters per second20 m/s × 3.6 = 72 km/h
- 100 meters per second100 m/s × 3.6 = 360 km/h

About the units
Meter per second (m/s)
The SI unit of speed. A brisk walk is about 1.5 m/s; Usain Bolt’s peak speed was about 12.4 m/s.
Kilometer per hour (km/h)
The road-speed unit in most of the world. Divide by 3.6 for m/s; 100 km/h is about 62 mph. One kilometer per hour equals 0.2777777778 meters per second (m/s).
Frequently asked questions
How many kilometers per hour are in one meter per second?
There are 3.6 kilometers per hour in one meter per second, and this value is exact by definition.
How do I convert meters per second to kilometers per hour?
Multiply the number of meters per second by 3.6. For example, 10 m/s × 3.6 = 36 km/h.
How many meters per second are in one kilometer per hour?
One kilometer per hour equals 0.2777777778 meters per second. That is the reverse factor, 1 ÷ 3.6.
What is 10 meters per second in kilometers per hour?
10 m/s = 36 km/h.
Is this m/s to km/h converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
