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 139.7 meters per second into feet per second we have to multiply 139.7 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

139.7 m/s → V_(ft/s)

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

V_(ft/s) = 139.7 m/s × 3.2808398950131 ft/s

V_(ft/s) = 458.33333333333 ft/s

The final result is:

139.7 m/s → 458.33333333333 ft/s

We conclude that 139.7 meters per second is equivalent to 458.33333333333 feet per second:

139.7 meters per second = 458.33333333333 feet per second
