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 1989 feet per second into knots we have to multiply 1989 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

1989 ft/s → V_(kt)

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

V_(kt) = 1989 ft/s × 0.59248380129641 kt

V_(kt) = 1178.4502807786 kt

The final result is:

1989 ft/s → 1178.4502807786 kt

We conclude that 1989 feet per second is equivalent to 1178.4502807786 knots:

1989 feet per second = 1178.4502807786 knots

Alternative conversion
