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 557 knots into feet per second we have to multiply 557 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

557 kt → V_(ft/s)

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

V_(ft/s) = 557 kt × 1.6878098570997 ft/s

V_(ft/s) = 940.11009040455 ft/s

The final result is:

557 kt → 940.11009040455 ft/s

We conclude that 557 knots is equivalent to 940.11009040455 feet per second:

557 knots = 940.11009040455 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 0.0010637052087907 × 557 knots.

Another way is saying that 557 knots is equal to 1 ÷ 0.0010637052087907 feet per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that five hundred fifty-seven knots is approximately nine hundred forty point one one feet per second:

557 kt ≅ 940.11 ft/s

An alternative is also that one foot per second is approximately zero point zero zero one times five hundred fifty-seven knots.
