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 9990 feet per second into knots we have to multiply 9990 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

9990 ft/s → V_(kt)

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

V_(kt) = 9990 ft/s × 0.59248380129641 kt

V_(kt) = 5918.9131749511 kt

The final result is:

9990 ft/s → 5918.9131749511 kt

We conclude that 9990 feet per second is equivalent to 5918.9131749511 knots:

9990 feet per second = 5918.9131749511 knots
