## 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 423 kilometers per hour into knots we have to multiply 423 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

423 km/h → V(kt)

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

V(kt) = 423 km/h × 0.53995680345662 kt

V(kt) = 228.40172786215 kt

The final result is:

423 km/h → 228.40172786215 kt

We conclude that 423 kilometers per hour is equivalent to 228.40172786215 knots:

423 kilometers per hour = 228.40172786215 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0043782505910093 × 423 kilometers per hour.

Another way is saying that 423 kilometers per hour is equal to 1 ÷ 0.0043782505910093 knots.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that four hundred twenty-three kilometers per hour is approximately two hundred twenty-eight point four zero two knots:

423 km/h ≅ 228.402 kt

An alternative is also that one knot is approximately zero point zero zero four times four hundred twenty-three kilometers per hour.
