Conversion formula

The conversion factor from feet per second to knots is 0.59248380129641, which means that 1 foot per second is equal to 0.59248380129641 knots:

1 ft/s = 0.59248380129641 kt

To convert 397 feet per second into knots we have to multiply 397 by the conversion factor in order to get the velocity amount from feet per second to knots. We can also form a simple proportion to calculate the result:

1 ft/s → 0.59248380129641 kt

397 ft/s → V(kt)

Solve the above proportion to obtain the velocity V in knots:

V(kt) = 397 ft/s × 0.59248380129641 kt

V(kt) = 235.21606911467 kt

The final result is:

397 ft/s → 235.21606911467 kt

We conclude that 397 feet per second is equivalent to 235.21606911467 knots:

397 feet per second = 235.21606911467 knots

Alternative conversion
