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 216.8 miles per hour into knots we have to multiply 216.8 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

216.8 mph → V_(kt)

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

V_(kt) = 216.8 mph × 0.8689762419014 kt

V_(kt) = 188.39404924422 kt

The final result is:

216.8 mph → 188.39404924422 kt

We conclude that 216.8 miles per hour is equivalent to 188.39404924422 knots:
