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 9 feet per second into knots we have to multiply 9 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

9 ft/s → V(kt)

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

V(kt) = 9 ft/s × 0.59248380129641 kt

V(kt) = 5.3323542116677 kt

The final result is:

9 ft/s → 5.3323542116677 kt

We conclude that 9 feet per second is equivalent to 5.3323542116677 knots:

9 feet per second = 5.3323542116677 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.18753442856664 × 9 feet per second.

Another way is saying that 9 feet per second is equal to 1 ÷ 0.18753442856664 knots.

Approximate result

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

9 ft/s ≅ 5.332 kt

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