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 4457 feet per second into knots we have to multiply 4457 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

4457 ft/s → V_(kt)

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

V_(kt) = 4457 ft/s × 0.59248380129641 kt

V_(kt) = 2640.7003023781 kt

The final result is:

4457 ft/s → 2640.7003023781 kt

We conclude that 4457 feet per second is equivalent to 2640.7003023781 knots:

4457 feet per second = 2640.7003023781 knots

Alternative conversion
