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 2809 feet per second into knots we have to multiply 2809 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

2809 ft/s → V_(kt)

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

V_(kt) = 2809 ft/s × 0.59248380129641 kt

V_(kt) = 1664.2869978416 kt

The final result is:

2809 ft/s → 1664.2869978416 kt

We conclude that 2809 feet per second is equivalent to 1664.2869978416 knots:

2809 feet per second = 1664.2869978416 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.00060085790569588 × 2809 feet per second.

Another way is saying that 2809 feet per second is equal to 1 ÷ 0.00060085790569588 knots.

Approximate result

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

2809 ft/s ≅ 1664.287 kt

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