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 6400 feet per second into knots we have to multiply 6400 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

6400 ft/s → V_(kt)

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

V_(kt) = 6400 ft/s × 0.59248380129641 kt

V_(kt) = 3791.896328297 kt

The final result is:

6400 ft/s → 3791.896328297 kt

We conclude that 6400 feet per second is equivalent to 3791.896328297 knots:

6400 feet per second = 3791.896328297 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.00026372029017183 × 6400 feet per second.

Another way is saying that 6400 feet per second is equal to 1 ÷ 0.00026372029017183 knots.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that six thousand four hundred feet per second is approximately three thousand seven hundred ninety-one point eight nine six knots:

6400 ft/s ≅ 3791.896 kt

An alternative is also that one knot is approximately zero times six thousand four hundred feet per second.
