Conversion formula

The conversion factor from knots to feet per second is 1.6878098570997, which means that 1 knot is equal to 1.6878098570997 feet per second:

1 kt = 1.6878098570997 ft/s

To convert 424 knots into feet per second we have to multiply 424 by the conversion factor in order to get the velocity amount from knots to feet per second. We can also form a simple proportion to calculate the result:

1 kt → 1.6878098570997 ft/s

424 kt → V_(ft/s)

Solve the above proportion to obtain the velocity V in feet per second:

V_(ft/s) = 424 kt × 1.6878098570997 ft/s

V_(ft/s) = 715.63137941029 ft/s

The final result is:

424 kt → 715.63137941029 ft/s

We conclude that 424 knots is equivalent to 715.63137941029 feet per second:

424 knots = 715.63137941029 feet per second

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 foot per second is equal to 0.0013973674558878 × 424 knots.

Another way is saying that 424 knots is equal to 1 ÷ 0.0013973674558878 feet per second.

Approximate result

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

424 kt ≅ 715.631 ft/s

An alternative is also that one foot per second is approximately zero point zero zero one times four hundred twenty-four knots.
