Feet per second to metres per second
Multiply feet per second by 0.3048 to get metres per second.
30 ft/s = 9.144 m/s
How to convert feet per second to metres per second
The metre per second is the SI unit of speed, one metre travelled per second. The foot per second is feet travelled per second, exactly 0.3048 m/s.
Worked example — 30 ft/s: 30 × 0.3048 = 9.144 m/s.

About feet per second and metres per second
Foot per second (ft/s)
1 ft/s = 0.3048 m/sDefinition. Feet travelled per second, exactly 0.3048 m/s
History and origin
The foot per second pairs the imperial foot with the second, and has long been used in mechanics and ballistics. It equals exactly 0.3048 metres per second.
Current use
Feet per second appear in physics problems and in ballistics, where muzzle velocities are often quoted this way.

Metre per second (m/s)
1 m/s = 3.2808 ft/sDefinition. The SI unit of speed, one metre travelled per second
History and origin
The metre per second is the coherent SI unit of speed, built directly from the base units of length and time. It is the natural choice wherever physics equations are involved.
Current use
Metres per second are used in science and engineering, and to report wind speed in meteorology.
