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 687.7 kilometers per hour into knots we have to multiply 687.7 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

687.7 km/h → V_(kt)

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

V_(kt) = 687.7 km/h × 0.53995680345662 kt

V_(kt) = 371.32829373712 kt

The final result is:

687.7 km/h → 371.32829373712 kt

We conclude that 687.7 kilometers per hour is equivalent to 371.32829373712 knots:

687.7 kilometers per hour = 371.32829373712 knots

Alternative conversion
