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 423.6 knots into feet per second we have to multiply 423.6 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

423.6 kt → V_(ft/s)

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

V_(ft/s) = 423.6 kt × 1.6878098570997 ft/s

V_(ft/s) = 714.95625546745 ft/s

The final result is:

423.6 kt → 714.95625546745 ft/s

We conclude that 423.6 knots is equivalent to 714.95625546745 feet per second:

423.6 knots = 714.95625546745 feet per second

Alternative conversion
