## 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 558 feet per second into knots we have to multiply 558 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

558 ft/s → V(kt)

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

V(kt) = 558 ft/s × 0.59248380129641 kt

V(kt) = 330.6059611234 kt

The final result is:

558 ft/s → 330.6059611234 kt

We conclude that 558 feet per second is equivalent to 330.6059611234 knots:

558 feet per second = 330.6059611234 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.003024748847849 × 558 feet per second.

Another way is saying that 558 feet per second is equal to 1 ÷ 0.003024748847849 knots.

## Approximate result

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

558 ft/s ≅ 330.606 kt

An alternative is also that one knot is approximately zero point zero zero three times five hundred fifty-eight feet per second.
