Conversion formula

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 39 miles per hour into knots we have to multiply 39 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

39 mph → V_(kt)

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

V_(kt) = 39 mph × 0.8689762419014 kt

V_(kt) = 33.890073434155 kt

The final result is:

39 mph → 33.890073434155 kt

We conclude that 39 miles per hour is equivalent to 33.890073434155 knots:

39 miles per hour = 33.890073434155 knots
