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 3490 decimeters into kilometers we have to multiply 3490 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

3490 dm → L_(km)

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

L_(km) = 3490 dm × 0.0001 km

L_(km) = 0.349 km

The final result is:

3490 dm → 0.349 km

We conclude that 3490 decimeters is equivalent to 0.349 kilometers:

3490 decimeters = 0.349 kilometers
