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 3489 decimeters into kilometers we have to multiply 3489 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

3489 dm → L_(km)

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

L_(km) = 3489 dm × 0.0001 km

L_(km) = 0.3489 km

The final result is:

3489 dm → 0.3489 km

We conclude that 3489 decimeters is equivalent to 0.3489 kilometers:

3489 decimeters = 0.3489 kilometers
