Meter per second quick reference
| Meter per second | Kilometer per hour | Mile per hour | Foot per second |
|---|---|---|---|
| 1 m/s | = 3.6 km/h | ≈ 2.236936292 mph | ≈ 3.280839895 ft/s |
| 10 m/s | = 36 km/h | ≈ 22.36936292 mph | ≈ 32.80839895 ft/s |
| 100 m/s | = 360 km/h | ≈ 223.6936292 mph | ≈ 328.0839895 ft/s |
| 1000 m/s | = 3600 km/h | ≈ 2236.936292 mph | ≈ 3280.839895 ft/s |
Where the meter per second fits
The next smaller speed unit is the knot (kn). 1 m/s ≈ 1.943844492 kn, and 1 kn ≈ 0.5144444444 m/s.
The next larger speed unit is the kilometer per second (km/s). 1 m/s = 0.001 km/s, and 1 km/s = 1000 m/s.
