Convert velocity and speed units including meters per second, feet per second, miles per hour, kilometers per hour, knots, inches per second, and more.
Meters per second to feet per second:
1 m/s = 3.28084 ft/s
Meters per second to kilometers per hour:
1 m/s = 3.6 km/h
Miles per hour to feet per second:
1 mph = 1.46667 ft/s
Knot to meters per second:
1 knot = 0.514444 m/s
Velocity conversions are useful for fluid velocity, vehicle speed, wind speed, pump systems, pipe flow, conveyor movement, machinery, and physics motion problems.
Use this converter when comparing metric, U.S. customary, aviation, and marine speed units.
Your result shows the entered velocity converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For engineering and physics work, make sure the velocity unit matches the equations, charts, equipment ratings, or flow formulas you are using.
Velocity is the rate of motion over distance, usually expressed as distance divided by time.
The SI unit of velocity is meters per second, abbreviated as m/s.
Speed measures how fast something moves, while velocity can also include direction. This converter handles the unit conversion for the magnitude.
One mile per hour equals approximately 1.46667 feet per second.
This converter is designed for velocity magnitude conversions, so it uses non-negative values.
