About This Conversion
Meters per second to kilometers per hour is the conversion between the SI unit used in physics and the unit used on the road. Multiplying by 3.6 is exact, since there are 3,600 seconds in an hour and 1,000 meters in a kilometer.
Wind speed is where this matters outside a physics class. Meteorological reports give wind in m/s in much of Europe and in km/h elsewhere, so a 25 m/s gust in a forecast is 90 km/h, comfortably a storm rather than a breeze.
Frequently Asked Questions
What is 1 m/s in km/h?
Exactly 3.6 km/h.
What is 10 m/s in km/h?
10 m/s is 36 km/h.
How fast is 25 m/s?
25 m/s is 90 km/h or 55.9 mph, a storm-force wind.
Why is the factor exactly 3.6?
One hour is 3,600 seconds and one kilometer is 1,000 meters, so the ratio is 3600/1000.
