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 688 decimeters into kilometers we have to multiply 688 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

688 dm → L_(km)

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

L_(km) = 688 dm × 0.0001 km

L_(km) = 0.0688 km

The final result is:

688 dm → 0.0688 km

We conclude that 688 decimeters is equivalent to 0.0688 kilometers:

688 decimeters = 0.0688 kilometers

Alternative conversion
