Conversion formula

The conversion factor from decimeters to kilometers is 0.0001, which means that 1 decimeter is equal to 0.0001 kilometers:

1 dm = 0.0001 km

To convert 6689 decimeters into kilometers we have to multiply 6689 by the conversion factor in order to get the length amount from decimeters to kilometers. We can also form a simple proportion to calculate the result:

1 dm → 0.0001 km

6689 dm → L_(km)

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

L_(km) = 6689 dm × 0.0001 km

L_(km) = 0.6689 km

The final result is:

6689 dm → 0.6689 km

We conclude that 6689 decimeters is equivalent to 0.6689 kilometers:
