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 28.7 kilometers per hour into knots we have to multiply 28.7 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

28.7 km/h → V_(kt)

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

V_(kt) = 28.7 km/h × 0.53995680345662 kt

V_(kt) = 15.496760259205 kt

The final result is:

28.7 km/h → 15.496760259205 kt

We conclude that 28.7 kilometers per hour is equivalent to 15.496760259205 knots:

28.7 kilometers per hour = 15.496760259205 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.064529616724631 × 28.7 kilometers per hour.

Another way is saying that 28.7 kilometers per hour is equal to 1 ÷ 0.064529616724631 knots.

Approximate result

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

28.7 km/h ≅ 15.497 kt

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