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 581 knots into feet per second we have to multiply 581 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

581 kt → V_(ft/s)

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

V_(ft/s) = 581 kt × 1.6878098570997 ft/s

V_(ft/s) = 980.61752697495 ft/s

The final result is:

581 kt → 980.61752697495 ft/s

We conclude that 581 knots is equivalent to 980.61752697495 feet per second:

581 knots = 980.61752697495 feet per second
