Convert wind speed between kilometers per hour, miles per hour, meters per second, knots, feet per second and other common wind-speed units.
Formula 'knots' failed: Unknown variable 'ms'
Wind speed can be expressed in several units depending on the application.
Kilometers per hour is common in many countries.
Miles per hour is common in the United States and some weather applications.
Knots are widely used in aviation and marine weather.
Meters per second is a standard SI unit for wind speed.
| Wind Speed | 10 |
| Input Unit | Kilometers per hour (km/h) |
10 km/h is approximately 6.21 mph, 2.78 m/s and 5.40 knots.
Try this example →| Wind Speed | 20 |
| Input Unit | Knots (kt) |
20 knots is approximately 37.04 km/h, 23.02 mph and 10.29 m/s.
Try this example →| Wind Speed | 10 |
| Input Unit | Meters per second (m/s) |
10 m/s equals 36 km/h, approximately 22.37 mph and 19.44 knots.
Try this example →One knot is approximately 1.852 km/h.
One knot is approximately 1.15078 mph.
One kilometer per hour equals approximately 0.277778 meters per second.
Knots are the standard wind-speed unit commonly used in aviation.
m/s means meters per second and is the SI unit of speed.
