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 423 knots into feet per second we have to multiply 423 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

423 kt → V_(ft/s)

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

V_(ft/s) = 423 kt × 1.6878098570997 ft/s

V_(ft/s) = 713.94356955319 ft/s

The final result is:

423 kt → 713.94356955319 ft/s

We conclude that 423 knots is equivalent to 713.94356955319 feet per second:

423 knots = 713.94356955319 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 0.0014006709250506 × 423 knots.

Another way is saying that 423 knots is equal to 1 ÷ 0.0014006709250506 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-three knots is approximately seven hundred thirteen point nine four four feet per second:

423 kt ≅ 713.944 ft/s

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