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 6.8 feet per second into miles per hour we have to multiply 6.8 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

6.8 ft/s → V(mph)

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

V(mph) = 6.8 ft/s × 0.68181818181818 mph

V(mph) = 4.6363636363636 mph

The final result is:

6.8 ft/s → 4.6363636363636 mph

We conclude that 6.8 feet per second is equivalent to 4.6363636363636 miles per hour:
