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 1128 feet per second into knots we have to multiply 1128 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

1128 ft/s → V_(kt)

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

V_(kt) = 1128 ft/s × 0.59248380129641 kt

V_(kt) = 668.32172786235 kt

The final result is:

1128 ft/s → 668.32172786235 kt

We conclude that 1128 feet per second is equivalent to 668.32172786235 knots:

1128 feet per second = 668.32172786235 knots

Alternative conversion
