Conversion formula

The conversion factor from kilometers per hour to knots is 0.53995680345662, which means that 1 kilometer per hour is equal to 0.53995680345662 knots:

1 km/h = 0.53995680345662 kt

To convert 509.5 kilometers per hour into knots we have to multiply 509.5 by the conversion factor in order to get the velocity amount from kilometers per hour to knots. We can also form a simple proportion to calculate the result:

1 km/h → 0.53995680345662 kt

509.5 km/h → V(kt)

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

V(kt) = 509.5 km/h × 0.53995680345662 kt

V(kt) = 275.10799136115 kt

The final result is:

509.5 km/h → 275.10799136115 kt

We conclude that 509.5 kilometers per hour is equivalent to 275.10799136115 knots:

509.5 kilometers per hour = 275.10799136115 knots
