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 389.8 decimeters into kilometers we have to multiply 389.8 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

389.8 dm → L_(km)

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

L_(km) = 389.8 dm × 0.0001 km

L_(km) = 0.03898 km

The final result is:

389.8 dm → 0.03898 km

We conclude that 389.8 decimeters is equivalent to 0.03898 kilometers:

389.8 decimeters = 0.03898 kilometers
