Instant, two-way conversion across common engineering units.
1 m/s = 3.6 km/h(Metres per second → Kilometres per hour)
To convert meters per second to kilometers per hour, multiply the value by 3.6. Speed conversions appear in wind loading, air velocity in ducts and transport analysis, where codes mix metric and imperial units.
Meters per second (m/s) is the SI derived unit of speed.
Kilometers per hour (km/h) is the everyday metric speed unit.
1 m/s equals 3.6 km/h.
Multiply the value by 3.6. For example, 10 m/s equals 36 km/h.
1 km/h equals 0.27777778 m/s. The converter above works in both directions, so you can type into either field.
Eurocode and most metric standards state basic wind speed in meters per second, while US standards such as ASCE 7 use miles per hour. Check the averaging period as well as the unit.
One knot is one nautical mile per hour, about 0.514 m/s. It is standard in marine works, aviation and meteorological data.
