Feet Per Second to Meters Per Second formula
Converting feet per second to meters per second is a single multiplication by 0.3048.
m/s = ft/s × 0.3048
Why this factor: the foot per second and the meter per second are both defined against the meter per second, so dividing one definition by the other gives 0.3048 directly. Both definitions are set out in full below.
To go the other way, divide by 0.3048 — or use the Meters Per Second to Feet Per Second converter, which is the same calculation reversed.
Worked example
Start with 30 ft/s. Multiply by 0.3048 to get 9.144 m/s.
30 ft/s × 0.3048 = 9.144 m/s
The converter above does this for any value you type, in either direction.
What is a foot per second?
Feet per second is a US engineering speed unit, common where distances are short.
Definition: Exactly 0.3048 meter per second, following from the exact definition of the foot.
Where it is used: Ballistics and muzzle velocities, fluid flow in pipes, and conveyor speeds in the US.
What is a meter per second?
Meters per second is the SI unit of speed, and the one physics equations expect.
Definition: Derived directly from the meter and the second.
Where it is used: Physics and engineering calculations, wind speed in meteorology, and sound and projectile velocities.
Feet Per Second vs Meters Per Second
The foot per second is an imperial unit while the meter per second is an SI unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
