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 457 kilometers per hour into knots we have to multiply 457 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

457 km/h → V_(kt)

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

V_(kt) = 457 km/h × 0.53995680345662 kt

V_(kt) = 246.76025917968 kt

The final result is:

457 km/h → 246.76025917968 kt

We conclude that 457 kilometers per hour is equivalent to 246.76025917968 knots:

457 kilometers per hour = 246.76025917968 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0040525164113718 × 457 kilometers per hour.

Another way is saying that 457 kilometers per hour is equal to 1 ÷ 0.0040525164113718 knots.

Approximate result

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

457 km/h ≅ 246.76 kt

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