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 490 knots into feet per second we have to multiply 490 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

490 kt → V_(ft/s)

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

V_(ft/s) = 490 kt × 1.6878098570997 ft/s

V_(ft/s) = 827.02682997887 ft/s

The final result is:

490 kt → 827.02682997887 ft/s

We conclude that 490 knots is equivalent to 827.02682997887 feet per second:

490 knots = 827.02682997887 feet per second
