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 431 knots into feet per second we have to multiply 431 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

431 kt → V_(ft/s)

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

V_(ft/s) = 431 kt × 1.6878098570997 ft/s

V_(ft/s) = 727.44604840999 ft/s

The final result is:

431 kt → 727.44604840999 ft/s

We conclude that 431 knots is equivalent to 727.44604840999 feet per second:

431 knots = 727.44604840999 feet per second

Alternative conversion
