Conversion formula

The conversion factor from miles per hour to feet per second is 1.4666666666667, which means that 1 mile per hour is equal to 1.4666666666667 feet per second:

1 mph = 1.4666666666667 ft/s

To convert 9997 miles per hour into feet per second we have to multiply 9997 by the conversion factor in order to get the velocity amount from miles per hour to feet per second. We can also form a simple proportion to calculate the result:

1 mph → 1.4666666666667 ft/s

9997 mph → V_(ft/s)

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

V_(ft/s) = 9997 mph × 1.4666666666667 ft/s

V_(ft/s) = 14662.266666667 ft/s

The final result is:

9997 mph → 14662.266666667 ft/s

We conclude that 9997 miles per hour is equivalent to 14662.266666667 feet per second:
