Conversion formula
The conversion factor from knots to kilometers per hour is 1.8519999999969, which means that 1 knot is equal to 1.8519999999969 kilometers per hour:
1 kt = 1.8519999999969 km/h
To convert 642 knots into kilometers per hour we have to multiply 642 by the conversion factor in order to get the velocity amount from knots to kilometers per hour. We can also form a simple proportion to calculate the result:
1 kt → 1.8519999999969 km/h
642 kt → V(km/h)
Solve the above proportion to obtain the velocity V in kilometers per hour:
V(km/h) = 642 kt × 1.8519999999969 km/h
V(km/h) = 1188.983999998 km/h
The final result is:
642 kt → 1188.983999998 km/h
We conclude that 642 knots is equivalent to 1188.983999998 kilometers per hour:
642 knots = 1188.983999998 kilometers per hour
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer per hour is equal to 0.00084105421099162 × 642 knots.
Another way is saying that 642 knots is equal to 1 ÷ 0.00084105421099162 kilometers per hour.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that six hundred forty-two knots is approximately one thousand one hundred eighty-eight point nine eight four kilometers per hour:
642 kt ≅ 1188.984 km/h
An alternative is also that one kilometer per hour is approximately zero point zero zero one times six hundred forty-two knots.
