Conversion formula

The conversion factor from knots to kilometers per hour is 1.8519999999969, which means that 1 knot is equal to 1.8519999999969 kilometers per hour:

1 kt = 1.8519999999969 km/h

To convert 428 knots into kilometers per hour we have to multiply 428 by the conversion factor in order to get the velocity amount from knots to kilometers per hour. We can also form a simple proportion to calculate the result:

1 kt → 1.8519999999969 km/h

428 kt → V_(km/h)

Solve the above proportion to obtain the velocity V in kilometers per hour:

V_(km/h) = 428 kt × 1.8519999999969 km/h

V_(km/h) = 792.65599999868 km/h

The final result is:

428 kt → 792.65599999868 km/h

We conclude that 428 knots is equivalent to 792.65599999868 kilometers per hour:

428 knots = 792.65599999868 kilometers per hour

Alternative conversion
