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 503.5 miles per hour into knots we have to multiply 503.5 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

503.5 mph → V_(kt)

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

V_(kt) = 503.5 mph × 0.8689762419014 kt

V_(kt) = 437.52953779735 kt

The final result is:

503.5 mph → 437.52953779735 kt

We conclude that 503.5 miles per hour is equivalent to 437.52953779735 knots:
