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 421.9 kilometers per hour into knots we have to multiply 421.9 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
421.9 km/h → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 421.9 km/h × 0.53995680345662 kt
V(kt) = 227.80777537835 kt
The final result is:
421.9 km/h → 227.80777537835 kt
We conclude that 421.9 kilometers per hour is equivalent to 227.80777537835 knots:
421.9 kilometers per hour = 227.80777537835 knots
