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 6440 feet per second into knots we have to multiply 6440 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

6440 ft/s → V_(kt)

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

V_(kt) = 6440 ft/s × 0.59248380129641 kt

V_(kt) = 3815.5956803489 kt

The final result is:

6440 ft/s → 3815.5956803489 kt

We conclude that 6440 feet per second is equivalent to 3815.5956803489 knots:

6440 feet per second = 3815.5956803489 knots
