## 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 688.3 kilometers per hour into knots we have to multiply 688.3 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

688.3 km/h → V(kt)

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

V(kt) = 688.3 km/h × 0.53995680345662 kt

V(kt) = 371.65226781919 kt

The final result is:

688.3 km/h → 371.65226781919 kt

We conclude that 688.3 kilometers per hour is equivalent to 371.65226781919 knots:

688.3 kilometers per hour = 371.65226781919 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0026906872003442 × 688.3 kilometers per hour.

Another way is saying that 688.3 kilometers per hour is equal to 1 ÷ 0.0026906872003442 knots.

## Approximate result

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

688.3 km/h ≅ 371.652 kt

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