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 628.8 kilometers per hour into knots we have to multiply 628.8 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

628.8 km/h → V(kt)

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

V(kt) = 628.8 km/h × 0.53995680345662 kt

V(kt) = 339.52483801352 kt

The final result is:

628.8 km/h → 339.52483801352 kt

We conclude that 628.8 kilometers per hour is equivalent to 339.52483801352 knots:
