## 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 21.4 kilometers per hour into knots we have to multiply 21.4 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

21.4 km/h → V(kt)

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

V(kt) = 21.4 km/h × 0.53995680345662 kt

V(kt) = 11.555075593972 kt

The final result is:

21.4 km/h → 11.555075593972 kt

We conclude that 21.4 kilometers per hour is equivalent to 11.555075593972 knots:

21.4 kilometers per hour = 11.555075593972 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.086542056074622 × 21.4 kilometers per hour.

Another way is saying that 21.4 kilometers per hour is equal to 1 ÷ 0.086542056074622 knots.

## Approximate result

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

21.4 km/h ≅ 11.555 kt

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