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 39.4 kilometers per hour into knots we have to multiply 39.4 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

39.4 km/h → V_(kt)

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

V_(kt) = 39.4 km/h × 0.53995680345662 kt

V_(kt) = 21.274298056191 kt

The final result is:

39.4 km/h → 21.274298056191 kt

We conclude that 39.4 kilometers per hour is equivalent to 21.274298056191 knots:

39.4 kilometers per hour = 21.274298056191 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.047005076142054 × 39.4 kilometers per hour.

Another way is saying that 39.4 kilometers per hour is equal to 1 ÷ 0.047005076142054 knots.

Approximate result

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

39.4 km/h ≅ 21.274 kt

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