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 422.4 knots into feet per second we have to multiply 422.4 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

422.4 kt → V_(ft/s)

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

V_(ft/s) = 422.4 kt × 1.6878098570997 ft/s

V_(ft/s) = 712.93088363893 ft/s

The final result is:

422.4 kt → 712.93088363893 ft/s

We conclude that 422.4 knots is equivalent to 712.93088363893 feet per second:

422.4 knots = 712.93088363893 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 0.0014026605144328 × 422.4 knots.

Another way is saying that 422.4 knots is equal to 1 ÷ 0.0014026605144328 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-two point four knots is approximately seven hundred twelve point nine three one feet per second:

422.4 kt ≅ 712.931 ft/s

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