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 420 kilometers per hour into knots we have to multiply 420 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

420 km/h → V_(kt)

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

V_(kt) = 420 km/h × 0.53995680345662 kt

V_(kt) = 226.78185745178 kt

The final result is:

420 km/h → 226.78185745178 kt

We conclude that 420 kilometers per hour is equivalent to 226.78185745178 knots:

420 kilometers per hour = 226.78185745178 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0044095238095165 × 420 kilometers per hour.

Another way is saying that 420 kilometers per hour is equal to 1 ÷ 0.0044095238095165 knots.

Approximate result

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

420 km/h ≅ 226.782 kt

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