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 402 miles per hour into knots we have to multiply 402 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

402 mph → V_(kt)

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

V_(kt) = 402 mph × 0.8689762419014 kt

V_(kt) = 349.32844924436 kt

The final result is:

402 mph → 349.32844924436 kt

We conclude that 402 miles per hour is equivalent to 349.32844924436 knots:
