Speed
Meters per Second to km/h
Convert between metres per second, km/h, mph and knots — the four speeds in common use.
How this is calculated
- km/h = m/s × 3.6
- m/s = mph × 0.44704
- 1 knot = 1 nautical mile per hour = 1.852 km/h
Checked against known values
- 1 m/s = 3.6 km/h
- 1 mph = 0.44704 m/s
- 1 kn = 1.852 km/h
- 10 m/s = 22.369363 mph
