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 558 knots into feet per second we have to multiply 558 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

558 kt → V_(ft/s)

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

V_(ft/s) = 558 kt × 1.6878098570997 ft/s

V_(ft/s) = 941.79790026165 ft/s

The final result is:

558 kt → 941.79790026165 ft/s

We conclude that 558 knots is equivalent to 941.79790026165 feet per second:

558 knots = 941.79790026165 feet per second
