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 397 decimeters into kilometers we have to multiply 397 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

397 dm → L_(km)

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

L_(km) = 397 dm × 0.0001 km

L_(km) = 0.0397 km

The final result is:

397 dm → 0.0397 km

We conclude that 397 decimeters is equivalent to 0.0397 kilometers:

397 decimeters = 0.0397 kilometers
