## 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 1085 feet per second into knots we have to multiply 1085 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

1085 ft/s → V(kt)

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

V(kt) = 1085 ft/s × 0.59248380129641 kt

V(kt) = 642.8449244066 kt

The final result is:

1085 ft/s → 642.8449244066 kt

We conclude that 1085 feet per second is equivalent to 642.8449244066 knots:

1085 feet per second = 642.8449244066 knots ## Alternative conversion
