## 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 309 feet per second into knots we have to multiply 309 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

309 ft/s → V(kt)

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

V(kt) = 309 ft/s × 0.59248380129641 kt

V(kt) = 183.07749460059 kt

The final result is:

309 ft/s → 183.07749460059 kt

We conclude that 309 feet per second is equivalent to 183.07749460059 knots:

309 feet per second = 183.07749460059 knots ## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0054621678223292 × 309 feet per second.

Another way is saying that 309 feet per second is equal to 1 ÷ 0.0054621678223292 knots.

## Approximate result

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

309 ft/s ≅ 183.077 kt

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