## 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 0.4 kilometers per hour into knots we have to multiply 0.4 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

0.4 km/h → V(kt)

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

V(kt) = 0.4 km/h × 0.53995680345662 kt

V(kt) = 0.21598272138265 kt

The final result is:

0.4 km/h → 0.21598272138265 kt

We conclude that 0.4 kilometers per hour is equivalent to 0.21598272138265 knots:

0.4 kilometers per hour = 0.21598272138265 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 4.6299999999923 × 0.4 kilometers per hour.

Another way is saying that 0.4 kilometers per hour is equal to 1 ÷ 4.6299999999923 knots.

## Approximate result

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

0.4 km/h ≅ 0.216 kt

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