Metres per second to feet per second

Multiply metres per second by 3.2808 to get feet per second.

1 m/s = 3.2808 ft/sNIST HB 44
m/s
49.2126ft/s

15 m/s = 49.2126 ft/s

How to convert metres per second to feet per second

The foot per second is feet travelled per second, exactly 0.3048 m/s. The metre per second is the SI unit of speed, one metre travelled per second.

Worked example — 15 m/s: 15 × 3.2808 = 49.2126 ft/s.

Reverse and related

About metres per second and feet per second

Metre per second (m/s)

1 m/s = 3.2808 ft/s

Definition. 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.

Foot per second (ft/s)

1 ft/s = 0.3048 m/s

Definition. 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.

Where people use this

Metres per second: physics, wind speed. Feet per second: ballistics, physics problems. 1 m/s is about 3.28 ft/s.

How we know this is right
The factor is fixed by the standards that define the units, not chosen — so it is exact, not a measurement:
1 ft/s = 0.3048 m/s, so 1 m/s = 1 ÷ 0.3048 = 3.2808 ft/s.

Every value is carried to full double precision; the display is rounded.

Both units are defined in NIST Handbook 44, Appendix C (Tables of Equivalents — international nautical mile); speeds derived from the exact mile, foot and hour.
