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 215 miles per hour into knots we have to multiply 215 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

215 mph → V_(kt)

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

V_(kt) = 215 mph × 0.8689762419014 kt

V_(kt) = 186.8298920088 kt

The final result is:

215 mph → 186.8298920088 kt

We conclude that 215 miles per hour is equivalent to 186.8298920088 knots:
