Conversion formula

The conversion factor from knots to feet per second is 1.6878098570997, which means that 1 knot is equal to 1.6878098570997 feet per second:

1 kt = 1.6878098570997 ft/s

To convert 3109 knots into feet per second we have to multiply 3109 by the conversion factor in order to get the velocity amount from knots to feet per second. We can also form a simple proportion to calculate the result:

1 kt → 1.6878098570997 ft/s

3109 kt → V_(ft/s)

Solve the above proportion to obtain the velocity V in feet per second:

V_(ft/s) = 3109 kt × 1.6878098570997 ft/s

V_(ft/s) = 5247.4008457231 ft/s

The final result is:

3109 kt → 5247.4008457231 ft/s

We conclude that 3109 knots is equivalent to 5247.4008457231 feet per second:

3109 knots = 5247.4008457231 feet per second

Alternative conversion
