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 8642 feet per second into knots we have to multiply 8642 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

8642 ft/s → V_(kt)

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

V_(kt) = 8642 ft/s × 0.59248380129641 kt

V_(kt) = 5120.2450108036 kt

The final result is:

8642 ft/s → 5120.2450108036 kt

We conclude that 8642 feet per second is equivalent to 5120.2450108036 knots:

8642 feet per second = 5120.2450108036 knots

Alternative conversion
