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 491.7 kilometers per hour into knots we have to multiply 491.7 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

491.7 km/h → V_(kt)

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

V_(kt) = 491.7 km/h × 0.53995680345662 kt

V_(kt) = 265.49676025962 kt

The final result is:

491.7 km/h → 265.49676025962 kt

We conclude that 491.7 kilometers per hour is equivalent to 265.49676025962 knots:

491.7 kilometers per hour = 265.49676025962 knots
