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 1129 feet per second into knots we have to multiply 1129 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

1129 ft/s → V_(kt)

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

V_(kt) = 1129 ft/s × 0.59248380129641 kt

V_(kt) = 668.91421166365 kt

The final result is:

1129 ft/s → 668.91421166365 kt

We conclude that 1129 feet per second is equivalent to 668.91421166365 knots:

1129 feet per second = 668.91421166365 knots

Alternative conversion
