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 664 knots into feet per second we have to multiply 664 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

664 kt → V_(ft/s)

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

V_(ft/s) = 664 kt × 1.6878098570997 ft/s

V_(ft/s) = 1120.7057451142 ft/s

The final result is:

664 kt → 1120.7057451142 ft/s

We conclude that 664 knots is equivalent to 1120.7057451142 feet per second:

664 knots = 1120.7057451142 feet per second

Alternative conversion
