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 9639 feet per second into knots we have to multiply 9639 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

9639 ft/s → V_(kt)

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

V_(kt) = 9639 ft/s × 0.59248380129641 kt

V_(kt) = 5710.9513606961 kt

The final result is:

9639 ft/s → 5710.9513606961 kt

We conclude that 9639 feet per second is equivalent to 5710.9513606961 knots:

9639 feet per second = 5710.9513606961 knots

Alternative conversion
