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 4009 knots into feet per second we have to multiply 4009 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

4009 kt → V_(ft/s)

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

V_(ft/s) = 4009 kt × 1.6878098570997 ft/s

V_(ft/s) = 6766.4297171128 ft/s

The final result is:

4009 kt → 6766.4297171128 ft/s

We conclude that 4009 knots is equivalent to 6766.4297171128 feet per second:

4009 knots = 6766.4297171128 feet per second

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 foot per second is equal to 0.00014778842636478 × 4009 knots.

Another way is saying that 4009 knots is equal to 1 ÷ 0.00014778842636478 feet per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that four thousand nine knots is approximately six thousand seven hundred sixty-six point four three feet per second:

4009 kt ≅ 6766.43 ft/s

An alternative is also that one foot per second is approximately zero times four thousand nine knots.
