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 8422 feet per second into knots we have to multiply 8422 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

8422 ft/s → V_(kt)

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

V_(kt) = 8422 ft/s × 0.59248380129641 kt

V_(kt) = 4989.8985745184 kt

The final result is:

8422 ft/s → 4989.8985745184 kt

We conclude that 8422 feet per second is equivalent to 4989.8985745184 knots:

8422 feet per second = 4989.8985745184 knots
