Conversion formula

The conversion factor from meters to kilometers is 0.001, which means that 1 meter is equal to 0.001 kilometers:

1 m = 0.001 km

To convert 642 meters into kilometers we have to multiply 642 by the conversion factor in order to get the length amount from meters to kilometers. We can also form a simple proportion to calculate the result:

1 m → 0.001 km

642 m → L_(km)

Solve the above proportion to obtain the length L in kilometers:

L_(km) = 642 m × 0.001 km

L_(km) = 0.642 km

The final result is:

642 m → 0.642 km

We conclude that 642 meters is equivalent to 0.642 kilometers:

642 meters = 0.642 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 1.5576323987539 × 642 meters.
