Conversion formula

The conversion factor from feet per second to knots is 0.59248380129641, which means that 1 foot per second is equal to 0.59248380129641 knots:

1 ft/s = 0.59248380129641 kt

To convert 9509 feet per second into knots we have to multiply 9509 by the conversion factor in order to get the velocity amount from feet per second to knots. We can also form a simple proportion to calculate the result:

1 ft/s → 0.59248380129641 kt

9509 ft/s → V_(kt)

Solve the above proportion to obtain the velocity V in knots:

V_(kt) = 9509 ft/s × 0.59248380129641 kt

V_(kt) = 5633.9284665275 kt

The final result is:

9509 ft/s → 5633.9284665275 kt

We conclude that 9509 feet per second is equivalent to 5633.9284665275 knots:

9509 feet per second = 5633.9284665275 knots

Alternative conversion
