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 685 feet per second into meters per second we have to multiply 685 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

685 ft/s → V_(m/s)

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

V_(m/s) = 685 ft/s × 0.3048 m/s

V_(m/s) = 208.788 m/s

The final result is:

685 ft/s → 208.788 m/s

We conclude that 685 feet per second is equivalent to 208.788 meters per second:

685 feet per second = 208.788 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 0.00478954729199 × 685 feet per second.

Another way is saying that 685 feet per second is equal to 1 ÷ 0.00478954729199 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 eighty-five feet per second is approximately two hundred eight point seven eight eight meters per second:

685 ft/s ≅ 208.788 m/s

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