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 1688 knots into feet per second we have to multiply 1688 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

1688 kt → V_(ft/s)

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

V_(ft/s) = 1688 kt × 1.6878098570997 ft/s

V_(ft/s) = 2849.0230387844 ft/s

The final result is:

1688 kt → 2849.0230387844 ft/s

We conclude that 1688 knots is equivalent to 2849.0230387844 feet per second:
