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 816 miles per hour into knots we have to multiply 816 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

816 mph → V_(kt)

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

V_(kt) = 816 mph × 0.8689762419014 kt

V_(kt) = 709.08461339154 kt

The final result is:

816 mph → 709.08461339154 kt

We conclude that 816 miles per hour is equivalent to 709.08461339154 knots:
