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 809 feet per second into knots we have to multiply 809 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

809 ft/s → V(kt)

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

V(kt) = 809 ft/s × 0.59248380129641 kt

V(kt) = 479.31939524879 kt

The final result is:

809 ft/s → 479.31939524879 kt

We conclude that 809 feet per second is equivalent to 479.31939524879 knots:

809 feet per second = 479.31939524879 knots

Alternative conversion
