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 4220 knots into feet per second we have to multiply 4220 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

4220 kt → V_(ft/s)

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

V_(ft/s) = 4220 kt × 1.6878098570997 ft/s

V_(ft/s) = 7122.5575969609 ft/s

The final result is:

4220 kt → 7122.5575969609 ft/s

We conclude that 4220 knots is equivalent to 7122.5575969609 feet per second:

4220 knots = 7122.5575969609 feet per second
