## Conversion formula

The conversion factor from feet per second to meters per second is 0.3048, which means that 1 foot per second is equal to 0.3048 meters per second:

1 ft/s = 0.3048 m/s

To convert 638 feet per second into meters per second we have to multiply 638 by the conversion factor in order to get the velocity amount from feet per second to meters per second. We can also form a simple proportion to calculate the result:

1 ft/s → 0.3048 m/s

638 ft/s → V(m/s)

Solve the above proportion to obtain the velocity V in meters per second:

V(m/s) = 638 ft/s × 0.3048 m/s

V(m/s) = 194.4624 m/s

The final result is:

638 ft/s → 194.4624 m/s

We conclude that 638 feet per second is equivalent to 194.4624 meters per second:

638 feet per second = 194.4624 meters per second

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter per second is equal to 0.0051423822805848 × 638 feet per second.

Another way is saying that 638 feet per second is equal to 1 ÷ 0.0051423822805848 meters per second.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that six hundred thirty-eight feet per second is approximately one hundred ninety-four point four six two meters per second:

638 ft/s ≅ 194.462 m/s

An alternative is also that one meter per second is approximately zero point zero zero five times six hundred thirty-eight feet per second.
