The conversion factor from miles per hour to knots is 0.8689762419014, which means that 1 mile per hour is equal to 0.8689762419014 knots:

1 mph = 0.8689762419014 kt

To convert 4040 miles per hour into knots we have to multiply 4040 by the conversion factor in order to get the velocity amount from miles per hour to knots. We can also form a simple proportion to calculate the result:

1 mph → 0.8689762419014 kt

4040 mph → V_(kt)

Solve the above proportion to obtain the velocity V in knots:

V_(kt) = 4040 mph × 0.8689762419014 kt

V_(kt) = 3510.6640172817 kt

The final result is:

4040 mph → 3510.6640172817 kt

We conclude that 4040 miles per hour is equivalent to 3510.6640172817 knots:
