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 489 knots into feet per second we have to multiply 489 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

489 kt → V_(ft/s)

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

V_(ft/s) = 489 kt × 1.6878098570997 ft/s

V_(ft/s) = 825.33902012177 ft/s

The final result is:

489 kt → 825.33902012177 ft/s

We conclude that 489 knots is equivalent to 825.33902012177 feet per second:

489 knots = 825.33902012177 feet per second
