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 6640 feet per second into knots we have to multiply 6640 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

6640 ft/s → V_(kt)

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

V_(kt) = 6640 ft/s × 0.59248380129641 kt

V_(kt) = 3934.0924406082 kt

The final result is:

6640 ft/s → 3934.0924406082 kt

We conclude that 6640 feet per second is equivalent to 3934.0924406082 knots:

6640 feet per second = 3934.0924406082 knots

Alternative conversion
