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 423 feet per second into knots we have to multiply 423 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

423 ft/s → V_(kt)

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

V_(kt) = 423 ft/s × 0.59248380129641 kt

V_(kt) = 250.62064794838 kt

The final result is:

423 ft/s → 250.62064794838 kt

We conclude that 423 feet per second is equivalent to 250.62064794838 knots:

423 feet per second = 250.62064794838 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0039900942248221 × 423 feet per second.

Another way is saying that 423 feet per second is equal to 1 ÷ 0.0039900942248221 knots.

Approximate result

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

423 ft/s ≅ 250.621 kt

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