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 1390 knots into feet per second we have to multiply 1390 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

1390 kt → V_(ft/s)

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

V_(ft/s) = 1390 kt × 1.6878098570997 ft/s

V_(ft/s) = 2346.0557013686 ft/s

The final result is:

1390 kt → 2346.0557013686 ft/s

We conclude that 1390 knots is equivalent to 2346.0557013686 feet per second:

1390 knots = 2346.0557013686 feet per second
