Conversion formula

The conversion factor from meters per second to feet per second is 3.2808398950131, which means that 1 meter per second is equal to 3.2808398950131 feet per second:

1 m/s = 3.2808398950131 ft/s

To convert 6689 meters per second into feet per second we have to multiply 6689 by the conversion factor in order to get the velocity amount from meters per second to feet per second. We can also form a simple proportion to calculate the result:

1 m/s → 3.2808398950131 ft/s

6689 m/s → V_(ft/s)

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

V_(ft/s) = 6689 m/s × 3.2808398950131 ft/s

V_(ft/s) = 21945.538057743 ft/s

The final result is:

6689 m/s → 21945.538057743 ft/s

We conclude that 6689 meters per second is equivalent to 21945.538057743 feet per second:

6689 meters per second = 21945.538057743 feet per second
