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 1391 feet per second into knots we have to multiply 1391 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

1391 ft/s → V_(kt)

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

V_(kt) = 1391 ft/s × 0.59248380129641 kt

V_(kt) = 824.1449676033 kt

The final result is:

1391 ft/s → 824.1449676033 kt

We conclude that 1391 feet per second is equivalent to 824.1449676033 knots:

1391 feet per second = 824.1449676033 knots

Alternative conversion
