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 1397 feet per second into knots we have to multiply 1397 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

1397 ft/s → V_(kt)

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

V_(kt) = 1397 ft/s × 0.59248380129641 kt

V_(kt) = 827.69987041108 kt

The final result is:

1397 ft/s → 827.69987041108 kt

We conclude that 1397 feet per second is equivalent to 827.69987041108 knots:

1397 feet per second = 827.69987041108 knots

Alternative conversion
