## 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 138 kilometers per hour into knots we have to multiply 138 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

138 km/h → V(kt)

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

V(kt) = 138 km/h × 0.53995680345662 kt

V(kt) = 74.514038877014 kt

The final result is:

138 km/h → 74.514038877014 kt

We conclude that 138 kilometers per hour is equivalent to 74.514038877014 knots:

138 kilometers per hour = 74.514038877014 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.01342028985505 × 138 kilometers per hour.

Another way is saying that 138 kilometers per hour is equal to 1 ÷ 0.01342028985505 knots.

## Approximate result

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

138 km/h ≅ 74.514 kt

An alternative is also that one knot is approximately zero point zero one three times one hundred thirty-eight kilometers per hour.
