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 4020 miles per hour into feet per second we have to multiply 4020 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

4020 mph → V_(ft/s)

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

V_(ft/s) = 4020 mph × 1.4666666666667 ft/s

V_(ft/s) = 5896 ft/s

The final result is:

4020 mph → 5896 ft/s

We conclude that 4020 miles per hour is equivalent to 5896 feet per second:
