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 4989 knots into feet per second we have to multiply 4989 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

4989 kt → V_(ft/s)

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

V_(ft/s) = 4989 kt × 1.6878098570997 ft/s

V_(ft/s) = 8420.4833770706 ft/s

The final result is:

4989 kt → 8420.4833770706 ft/s

We conclude that 4989 knots is equivalent to 8420.4833770706 feet per second:
