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 428 kilometers per hour into knots we have to multiply 428 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

428 km/h → V(kt)

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

V(kt) = 428 km/h × 0.53995680345662 kt

V(kt) = 231.10151187943 kt

The final result is:

428 km/h → 231.10151187943 kt

We conclude that 428 kilometers per hour is equivalent to 231.10151187943 knots:

428 kilometers per hour = 231.10151187943 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0043271028037311 × 428 kilometers per hour.

Another way is saying that 428 kilometers per hour is equal to 1 ÷ 0.0043271028037311 knots.

Approximate result

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

428 km/h ≅ 231.102 kt

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