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 1688 decimeters into kilometers we have to multiply 1688 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

1688 dm → L_(km)

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

L_(km) = 1688 dm × 0.0001 km

L_(km) = 0.1688 km

The final result is:

1688 dm → 0.1688 km

We conclude that 1688 decimeters is equivalent to 0.1688 kilometers:

1688 decimeters = 0.1688 kilometers
