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 6.4 feet per second into knots we have to multiply 6.4 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

6.4 ft/s → V_(kt)

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

V_(kt) = 6.4 ft/s × 0.59248380129641 kt

V_(kt) = 3.791896328297 kt

The final result is:

6.4 ft/s → 3.791896328297 kt

We conclude that 6.4 feet per second is equivalent to 3.791896328297 knots:

6.4 feet per second = 3.791896328297 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.26372029017183 × 6.4 feet per second.

Another way is saying that 6.4 feet per second is equal to 1 ÷ 0.26372029017183 knots.

Approximate result

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

6.4 ft/s ≅ 3.792 kt

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