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 680.4 meters into kilometers we have to multiply 680.4 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

680.4 m → L_(km)

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

L_(km) = 680.4 m × 0.001 km

L_(km) = 0.6804 km

The final result is:

680.4 m → 0.6804 km

We conclude that 680.4 meters is equivalent to 0.6804 kilometers:

680.4 meters = 0.6804 kilometers
