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 3457 decimeters into kilometers we have to multiply 3457 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

3457 dm → L_(km)

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

L_(km) = 3457 dm × 0.0001 km

L_(km) = 0.3457 km

The final result is:

3457 dm → 0.3457 km

We conclude that 3457 decimeters is equivalent to 0.3457 kilometers:
