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 624.9 miles per hour into knots we have to multiply 624.9 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

624.9 mph → V_(kt)

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

V_(kt) = 624.9 mph × 0.8689762419014 kt

V_(kt) = 543.02325356418 kt

The final result is:

624.9 mph → 543.02325356418 kt

We conclude that 624.9 miles per hour is equivalent to 543.02325356418 knots:
