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 17.9 miles per hour into knots we have to multiply 17.9 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

17.9 mph → V_(kt)

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

V_(kt) = 17.9 mph × 0.8689762419014 kt

V_(kt) = 15.554674730035 kt

The final result is:

17.9 mph → 15.554674730035 kt

We conclude that 17.9 miles per hour is equivalent to 15.554674730035 knots:
