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 1 mile per hour into knots we have to multiply 1 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

1 mph → V_(kt)

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

V_(kt) = 1 mph × 0.8689762419014 kt

V_(kt) = 0.8689762419014 kt

The final result is:

1 mph → 0.8689762419014 kt

We conclude that 1 mile per hour is equivalent to 0.8689762419014 knots:

1 mile per hour = 0.8689762419014 knots
