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 511 kilometers per hour into knots we have to multiply 511 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

511 km/h → V_(kt)

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

V_(kt) = 511 km/h × 0.53995680345662 kt

V_(kt) = 275.91792656633 kt

The final result is:

511 km/h → 275.91792656633 kt

We conclude that 511 kilometers per hour is equivalent to 275.91792656633 knots:

511 kilometers per hour = 275.91792656633 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0036242661448081 × 511 kilometers per hour.

Another way is saying that 511 kilometers per hour is equal to 1 ÷ 0.0036242661448081 knots.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that five hundred eleven kilometers per hour is approximately two hundred seventy-five point nine one eight knots:

511 km/h ≅ 275.918 kt

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