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 4 feet per second into miles per hour we have to multiply 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

4 ft/s → V(mph)

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

V(mph) = 4 ft/s × 0.68181818181818 mph

V(mph) = 2.7272727272727 mph

The final result is:

4 ft/s → 2.7272727272727 mph

We conclude that 4 feet per second is equivalent to 2.7272727272727 miles per hour:
