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 997.8 kilometers per hour into knots we have to multiply 997.8 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

997.8 km/h → V_(kt)

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

V_(kt) = 997.8 km/h × 0.53995680345662 kt

V_(kt) = 538.76889848902 kt

The final result is:

997.8 km/h → 538.76889848902 kt

We conclude that 997.8 kilometers per hour is equivalent to 538.76889848902 knots:

997.8 kilometers per hour = 538.76889848902 knots

Alternative conversion
