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 8685 feet per second into knots we have to multiply 8685 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

8685 ft/s → V_(kt)

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

V_(kt) = 8685 ft/s × 0.59248380129641 kt

V_(kt) = 5145.7218142593 kt

The final result is:

8685 ft/s → 5145.7218142593 kt

We conclude that 8685 feet per second is equivalent to 5145.7218142593 knots:

8685 feet per second = 5145.7218142593 knots
