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 4.2 kilometers per hour into knots we have to multiply 4.2 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

4.2 km/h → V_(kt)

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

V_(kt) = 4.2 km/h × 0.53995680345662 kt

V_(kt) = 2.2678185745178 kt

The final result is:

4.2 km/h → 2.2678185745178 kt

We conclude that 4.2 kilometers per hour is equivalent to 2.2678185745178 knots:

4.2 kilometers per hour = 2.2678185745178 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.44095238095165 × 4.2 kilometers per hour.

Another way is saying that 4.2 kilometers per hour is equal to 1 ÷ 0.44095238095165 knots.

Approximate result

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

4.2 km/h ≅ 2.268 kt

An alternative is also that one knot is approximately zero point four four one times four point two kilometers per hour.
