How to use it
- Type the value in the meters per second box.
- Read the result in feet per second as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
ft/s = m/s × 3.280839895
Multiply the value in meters per second by 3.280839895 to get feet per second.
Example
To convert 25 m/s to feet per second: 25 × 3.280839895 = 82.021 ft/s.

About the units
- Meter per second
- The SI unit of speed: covering a distance of one meter in one second.
- Foot per second
- Covering one international foot (0.3048 m) in one second, exactly 0.3048 m/s. It appears in ballistics and US engineering.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many feet per second are in one meter per second?
1 m/s = 3.28084 ft/s exactly.
How do I convert meters per second to feet per second?
Use ft/s = m/s × 3.280839895. For example, 25 m/s = 82.021 ft/s.
How many meters per second are in one foot per second?
1 ft/s = 0.3048 m/s.
How do I convert km/h to m/s in my head?
Divide by 3.6, because an hour is 3600 seconds and a kilometer is 1000 meters. For example 72 km/h is 20 m/s; multiply by 3.6 to go back.
Why do Mach values differ between sources?
The speed of sound depends on air temperature. We use 340.294 m/s at sea level and 15 °C; at 11 km altitude it is about 295 m/s, so Mach 1 is slower there.
