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 1139 feet per second into knots we have to multiply 1139 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

1139 ft/s → V_(kt)

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

V_(kt) = 1139 ft/s × 0.59248380129641 kt

V_(kt) = 674.83904967661 kt

The final result is:

1139 ft/s → 674.83904967661 kt

We conclude that 1139 feet per second is equivalent to 674.83904967661 knots:

1139 feet per second = 674.83904967661 knots
