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 5421 knots into feet per second we have to multiply 5421 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

5421 kt → V_(ft/s)

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

V_(ft/s) = 5421 kt × 1.6878098570997 ft/s

V_(ft/s) = 9149.6172353377 ft/s

The final result is:

5421 kt → 9149.6172353377 ft/s

We conclude that 5421 knots is equivalent to 9149.6172353377 feet per second:

5421 knots = 9149.6172353377 feet per second
