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 4080 knots into feet per second we have to multiply 4080 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

4080 kt → V_(ft/s)

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

V_(ft/s) = 4080 kt × 1.6878098570997 ft/s

V_(ft/s) = 6886.2642169669 ft/s

The final result is:

4080 kt → 6886.2642169669 ft/s

We conclude that 4080 knots is equivalent to 6886.2642169669 feet per second:

4080 knots = 6886.2642169669 feet per second

Alternative conversion
