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 668 knots into feet per second we have to multiply 668 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

668 kt → V_(ft/s)

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

V_(ft/s) = 668 kt × 1.6878098570997 ft/s

V_(ft/s) = 1127.4569845426 ft/s

The final result is:

668 kt → 1127.4569845426 ft/s

We conclude that 668 knots is equivalent to 1127.4569845426 feet per second:

668 knots = 1127.4569845426 feet per second
