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 4309 feet per second into knots we have to multiply 4309 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

4309 ft/s → V_(kt)

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

V_(kt) = 4309 ft/s × 0.59248380129641 kt

V_(kt) = 2553.0126997862 kt

The final result is:

4309 ft/s → 2553.0126997862 kt

We conclude that 4309 feet per second is equivalent to 2553.0126997862 knots:

4309 feet per second = 2553.0126997862 knots

Alternative conversion
