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 4021 knots into feet per second we have to multiply 4021 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

4021 kt → V_(ft/s)

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

V_(ft/s) = 4021 kt × 1.6878098570997 ft/s

V_(ft/s) = 6786.683435398 ft/s

The final result is:

4021 kt → 6786.683435398 ft/s

We conclude that 4021 knots is equivalent to 6786.683435398 feet per second:

4021 knots = 6786.683435398 feet per second

Alternative conversion
