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 1255 kilometers per hour into knots we have to multiply 1255 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

1255 km/h → V_(kt)

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

V_(kt) = 1255 km/h × 0.53995680345662 kt

V_(kt) = 677.64578833806 kt

The final result is:

1255 km/h → 677.64578833806 kt

We conclude that 1255 kilometers per hour is equivalent to 677.64578833806 knots:

1255 kilometers per hour = 677.64578833806 knots

Alternative conversion
