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 3478 decimeters into kilometers we have to multiply 3478 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

3478 dm → L_(km)

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

L_(km) = 3478 dm × 0.0001 km

L_(km) = 0.3478 km

The final result is:

3478 dm → 0.3478 km

We conclude that 3478 decimeters is equivalent to 0.3478 kilometers:

3478 decimeters = 0.3478 kilometers
