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 6647 feet per second into knots we have to multiply 6647 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

6647 ft/s → V_(kt)

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

V_(kt) = 6647 ft/s × 0.59248380129641 kt

V_(kt) = 3938.2398272172 kt

The final result is:

6647 ft/s → 3938.2398272172 kt

We conclude that 6647 feet per second is equivalent to 3938.2398272172 knots:

6647 feet per second = 3938.2398272172 knots

Alternative conversion
