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 6421 meters per second into feet per second we have to multiply 6421 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

6421 m/s → V_(ft/s)

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

V_(ft/s) = 6421 m/s × 3.2808398950131 ft/s

V_(ft/s) = 21066.272965879 ft/s

The final result is:

6421 m/s → 21066.272965879 ft/s

We conclude that 6421 meters per second is equivalent to 21066.272965879 feet per second:

6421 meters per second = 21066.272965879 feet per second
