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 939 feet per second into knots we have to multiply 939 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

939 ft/s → V_(kt)

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

V_(kt) = 939 ft/s × 0.59248380129641 kt

V_(kt) = 556.34228941733 kt

The final result is:

939 ft/s → 556.34228941733 kt

We conclude that 939 feet per second is equivalent to 556.34228941733 knots:

939 feet per second = 556.34228941733 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0017974545869007 × 939 feet per second.

Another way is saying that 939 feet per second is equal to 1 ÷ 0.0017974545869007 knots.

Approximate result

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

939 ft/s ≅ 556.342 kt

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