## Conversion formula

The conversion factor from feet per second to miles per hour is 0.68181818181818, which means that 1 foot per second is equal to 0.68181818181818 miles per hour:

1 ft/s = 0.68181818181818 mph

To convert 15.4 feet per second into miles per hour we have to multiply 15.4 by the conversion factor in order to get the velocity amount from feet per second to miles per hour. We can also form a simple proportion to calculate the result:

1 ft/s → 0.68181818181818 mph

15.4 ft/s → V(mph)

Solve the above proportion to obtain the velocity V in miles per hour:

V(mph) = 15.4 ft/s × 0.68181818181818 mph

V(mph) = 10.5 mph

The final result is:

15.4 ft/s → 10.5 mph
