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 9489 feet per second into knots we have to multiply 9489 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

9489 ft/s → V_(kt)

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

V_(kt) = 9489 ft/s × 0.59248380129641 kt

V_(kt) = 5622.0787905016 kt

The final result is:

9489 ft/s → 5622.0787905016 kt

We conclude that 9489 feet per second is equivalent to 5622.0787905016 knots:

9489 feet per second = 5622.0787905016 knots
