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 1640 knots into feet per second we have to multiply 1640 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

1640 kt → V_(ft/s)

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

V_(ft/s) = 1640 kt × 1.6878098570997 ft/s

V_(ft/s) = 2768.0081656436 ft/s

The final result is:

1640 kt → 2768.0081656436 ft/s

We conclude that 1640 knots is equivalent to 2768.0081656436 feet per second:

1640 knots = 2768.0081656436 feet per second

Alternative conversion
