## 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 397.1 kilometers per hour into knots we have to multiply 397.1 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

397.1 km/h → V(kt)

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

V(kt) = 397.1 km/h × 0.53995680345662 kt

V(kt) = 214.41684665262 kt

The final result is:

397.1 km/h → 214.41684665262 kt

We conclude that 397.1 kilometers per hour is equivalent to 214.41684665262 knots:

397.1 kilometers per hour = 214.41684665262 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0046638126416442 × 397.1 kilometers per hour.

Another way is saying that 397.1 kilometers per hour is equal to 1 ÷ 0.0046638126416442 knots.

## Approximate result

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

397.1 km/h ≅ 214.417 kt

An alternative is also that one knot is approximately zero point zero zero five times three hundred ninety-seven point one kilometers per hour.
