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 1109 feet per second into knots we have to multiply 1109 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

1109 ft/s → V_(kt)

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

V_(kt) = 1109 ft/s × 0.59248380129641 kt

V_(kt) = 657.06453563772 kt

The final result is:

1109 ft/s → 657.06453563772 kt

We conclude that 1109 feet per second is equivalent to 657.06453563772 knots:

1109 feet per second = 657.06453563772 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0015219205203785 × 1109 feet per second.

Another way is saying that 1109 feet per second is equal to 1 ÷ 0.0015219205203785 knots.

Approximate result

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

1109 ft/s ≅ 657.065 kt

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