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 438 feet per second into knots we have to multiply 438 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

438 ft/s → V_(kt)

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

V_(kt) = 438 ft/s × 0.59248380129641 kt

V_(kt) = 259.50790496783 kt

The final result is:

438 ft/s → 259.50790496783 kt

We conclude that 438 feet per second is equivalent to 259.50790496783 knots:

438 feet per second = 259.50790496783 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0038534471623282 × 438 feet per second.

Another way is saying that 438 feet per second is equal to 1 ÷ 0.0038534471623282 knots.

Approximate result

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

438 ft/s ≅ 259.508 kt

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