Foot/Second to Meter/Second (ft/s to m/s)
Result
0.3048 Meter/Second
Formula
m/s = ft/s × 0.3048
1 ft/s = 0.3048 m/s, and 1 m/s = 3.280839895 ft/s.
Speed units are a length divided by a time: 1 km/h = 1/3.6 m/s, 1 mph = 0.44704 m/s exactly, and 1 knot = 1 nautical mile per hour = 1,852/3,600 m/s.
Worked examples
- 1 ft/s × 0.3048 = 0.3048 m/s
- 10 ft/s × 0.3048 = 3.048 m/s
- 100 ft/s × 0.3048 = 30.48 m/s
Common mistakes
- A knot is a nautical mile per hour, so 1 kn = 1.852 km/h and 1.15078 mph — not 1 mph.
- Weather services quote wind in km/h, m/s, mph or knots depending on country; check the unit before comparing forecasts.
