## 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 39.9 feet per second into knots we have to multiply 39.9 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

39.9 ft/s → V(kt)

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

V(kt) = 39.9 ft/s × 0.59248380129641 kt

V(kt) = 23.640103671727 kt

The final result is:

39.9 ft/s → 23.640103671727 kt

We conclude that 39.9 feet per second is equivalent to 23.640103671727 knots:

39.9 feet per second = 23.640103671727 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.042300998924805 × 39.9 feet per second.

Another way is saying that 39.9 feet per second is equal to 1 ÷ 0.042300998924805 knots.

## Approximate result

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

39.9 ft/s ≅ 23.64 kt

An alternative is also that one knot is approximately zero point zero four two times thirty-nine point nine feet per second.
