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 2640 feet per second into knots we have to multiply 2640 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

2640 ft/s → V_(kt)

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

V_(kt) = 2640 ft/s × 0.59248380129641 kt

V_(kt) = 1564.1572354225 kt

The final result is:

2640 ft/s → 1564.1572354225 kt

We conclude that 2640 feet per second is equivalent to 1564.1572354225 knots:

2640 feet per second = 1564.1572354225 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.00063932191556808 × 2640 feet per second.

Another way is saying that 2640 feet per second is equal to 1 ÷ 0.00063932191556808 knots.

Approximate result

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

2640 ft/s ≅ 1564.157 kt

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