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 989 knots into feet per second we have to multiply 989 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

989 kt → V_(ft/s)

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

V_(ft/s) = 989 kt × 1.6878098570997 ft/s

V_(ft/s) = 1669.2439486716 ft/s

The final result is:

989 kt → 1669.2439486716 ft/s

We conclude that 989 knots is equivalent to 1669.2439486716 feet per second:
