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 1685 knots into feet per second we have to multiply 1685 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

1685 kt → V_(ft/s)

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

V_(ft/s) = 1685 kt × 1.6878098570997 ft/s

V_(ft/s) = 2843.9596092131 ft/s

The final result is:

1685 kt → 2843.9596092131 ft/s

We conclude that 1685 knots is equivalent to 2843.9596092131 feet per second:

1685 knots = 2843.9596092131 feet per second
