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 4509 feet per second into knots we have to multiply 4509 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

4509 ft/s → V_(kt)

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

V_(kt) = 4509 ft/s × 0.59248380129641 kt

V_(kt) = 2671.5094600455 kt

The final result is:

4509 ft/s → 2671.5094600455 kt

We conclude that 4509 feet per second is equivalent to 2671.5094600455 knots:

4509 feet per second = 2671.5094600455 knots

Alternative conversion
