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 8109 feet per second into knots we have to multiply 8109 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

8109 ft/s → V_(kt)

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

V_(kt) = 8109 ft/s × 0.59248380129641 kt

V_(kt) = 4804.4511447126 kt

The final result is:

8109 ft/s → 4804.4511447126 kt

We conclude that 8109 feet per second is equivalent to 4804.4511447126 knots:

8109 feet per second = 4804.4511447126 knots

Alternative conversion
