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 431 feet per second into knots we have to multiply 431 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

431 ft/s → V_(kt)

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

V_(kt) = 431 ft/s × 0.59248380129641 kt

V_(kt) = 255.36051835875 kt

The final result is:

431 ft/s → 255.36051835875 kt

We conclude that 431 feet per second is equivalent to 255.36051835875 knots:

431 feet per second = 255.36051835875 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0039160321510435 × 431 feet per second.

Another way is saying that 431 feet per second is equal to 1 ÷ 0.0039160321510435 knots.

Approximate result

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

431 ft/s ≅ 255.361 kt

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