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 3640 feet per second into knots we have to multiply 3640 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

3640 ft/s → V_(kt)

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

V_(kt) = 3640 ft/s × 0.59248380129641 kt

V_(kt) = 2156.6410367189 kt

The final result is:

3640 ft/s → 2156.6410367189 kt

We conclude that 3640 feet per second is equivalent to 2156.6410367189 knots:

3640 feet per second = 2156.6410367189 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.00046368402667575 × 3640 feet per second.

Another way is saying that 3640 feet per second is equal to 1 ÷ 0.00046368402667575 knots.

Approximate result

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

3640 ft/s ≅ 2156.641 kt

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