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 396 knots into feet per second we have to multiply 396 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

396 kt → V_(ft/s)

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

V_(ft/s) = 396 kt × 1.6878098570997 ft/s

V_(ft/s) = 668.3727034115 ft/s

The final result is:

396 kt → 668.3727034115 ft/s

We conclude that 396 knots is equivalent to 668.3727034115 feet per second:

396 knots = 668.3727034115 feet per second

Alternative conversion
