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 509 feet per second into knots we have to multiply 509 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

509 ft/s → V_(kt)

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

V_(kt) = 509 ft/s × 0.59248380129641 kt

V_(kt) = 301.57425485987 kt

The final result is:

509 ft/s → 301.57425485987 kt

We conclude that 509 feet per second is equivalent to 301.57425485987 knots:

509 feet per second = 301.57425485987 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0033159329216105 × 509 feet per second.

Another way is saying that 509 feet per second is equal to 1 ÷ 0.0033159329216105 knots.

Approximate result

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

509 ft/s ≅ 301.574 kt

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