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 9978 feet per second into knots we have to multiply 9978 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

9978 ft/s → V_(kt)

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

V_(kt) = 9978 ft/s × 0.59248380129641 kt

V_(kt) = 5911.8033693356 kt

The final result is:

9978 ft/s → 5911.8033693356 kt

We conclude that 9978 feet per second is equivalent to 5911.8033693356 knots:
