## 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 15.5 feet per second into knots we have to multiply 15.5 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

15.5 ft/s → V(kt)

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

V(kt) = 15.5 ft/s × 0.59248380129641 kt

V(kt) = 9.1834989200943 kt

The final result is:

15.5 ft/s → 9.1834989200943 kt

We conclude that 15.5 feet per second is equivalent to 9.1834989200943 knots:

15.5 feet per second = 9.1834989200943 knots ## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.10889095852256 × 15.5 feet per second.

Another way is saying that 15.5 feet per second is equal to 1 ÷ 0.10889095852256 knots.

## Approximate result

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

15.5 ft/s ≅ 9.183 kt

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