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 709 miles per hour into knots we have to multiply 709 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

709 mph → V_(kt)

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

V_(kt) = 709 mph × 0.8689762419014 kt

V_(kt) = 616.10415550809 kt

The final result is:

709 mph → 616.10415550809 kt

We conclude that 709 miles per hour is equivalent to 616.10415550809 knots:
